Jim Cummings is widely considered to be a successor to the late Creator/MelBlanc. He speaks in a deep, gravelly voice for most roles, but can do many variations of it. His skills as a mimic have earned him scores of opportunities at Walt Disney Productions, in particular. At Creator/{{Disney}}, Cummings not only replaced the ailing Sterling Holloway as the voice of Winnie-the-Pooh, but later took over as the voice of Tigger when well-known ventriloquist and voice actor Creator/PaulWinchell retired, and also voiced Crud. Cummings was hired to sing the last part of the song "Be Prepared" in ''Disney/TheLionKing'' after actor Creator/JeremyIrons pulled his vocal chords, and he also voiced Ed the Hyena. He also sang for another non-singing actor Christopher Lloyd for the song, "In the Dark of the Night" in the animated film, ''WesternAnimation/{{Anastasia}}''. He also played the star of the series ''WesternAnimation/DarkwingDuck''

Cummings is the only original ''Franchise/TeenageMutantNinjaTurtles'' voice actor to return for the 2007 movie. His first three TMNT appearances were ''[[WesternAnimation/TeenageMutantNinjaTurtles1987 Teenage Mutant Ninja Turtles]]'', ''WesternAnimation/CartoonAllStarsToTheRescue'', and ''VideoGame/TeenageMutantNinjaTurtlesTurtlesInTime''. The 2007 movie was Cummings' sixth computer-animated movie appearance. His first five computer-animated movie appearances included ''WesternAnimation/{{Antz}}'', ''TheNuttiestNutcracker'', ''WesternAnimation/{{Shrek}}'', ''WesternAnimation/JimmyNeutronBoyGenius'', and ''Mickey's Twice Upon a Christmas''; and his latest animated movie appearances are ''WesternAnimation/BeeMovie'', ''Franchise/{{Bionicle}}: The Legend Reborn'', and ''Disney/ThePrincessAndTheFrog''.

In the course of two decades, Cummings' career as a voice actor has taken him from bit parts to leading roles in major series at various studios, including Creator/{{Nickelodeon}}, Creator/WarnerBros, Creator/HannaBarbera, Creator/{{Dreamworks}}, and Creator/TwentiethCenturyFox studios. His most memorable roles, however, have been at Walt Creator/{{Disney}} Studios. There, he provided voices for a variety of television series, including leading roles in Disney's ''WesternAnimation/AdventuresOfTheGummiBears'', (taking over the character of Zummi Gummi after Creator/PaulWinchell's departure from the role), ''WesternAnimation/DuckTales'', ''WesternAnimation/ChipNDaleRescueRangers'' [[note]]voicing Fat Cat, Professor Nimnul, and was the second voice for Monterey Jack, replacing Creator/PeterCullen, even though Cummings voiced Monty in the pilot movie, "To The Rescue"[[/note]], ''WesternAnimation/DarkwingDuck'', ''WesternAnimation/GoofTroop'', ''WesternAnimation/{{Bonkers}}'' (voicing [[TalkingToHimself both Bonkers and Lucky]] -- until Lucky Piquel was replaced with a female cop named Miranda Wright), ''WesternAnimation/{{Gargoyles}}'', and ''HouseOfMouse'', and movies such as ''Disney/{{Hercules}}'', ''Disney/TheHunchbackOfNotreDame'', ''Disney/{{Pocahontas}}'' and the Disney special edition of ''Disney/AliceInWonderland'' (as the Cheshire Cat singing "I'm Odd"). Cummings also voiced the non-speaking roles of Ed the laughing hyena in 1994's ''Disney/TheLionKing'' and Duncan the horse on ''WesternAnimation/TheSimpsons'' episode "Saddlesore Galactica".

Other notable roles include "Mr. Bumpy" in the cult Claymation show ''WesternAnimation/BumpInTheNight'', Dr. Robotnik on ''WesternAnimation/SonicSatAM'' (in both the dramatic, action-oriented [=SatAM=] adaptation and in the unaired pilot of the wacky, ''WesternAnimation/LooneyTunes''-esque syndicated series), Mayor Manx on ''WesternAnimation/SWATKats'', Psy-Crow and Bob the Killer Goldfish on ''WesternAnimation/EarthwormJim'' and Taz the Tazmanian Devil on ''WesternAnimation/TazMania'' and a number of other projects.

In addition to Taz and Pooh, Cummings has over the years become the official voice for a number of legendary cartoon characters, including Tigger, Pete, Humphrey the Bear, Dick Dastardly, the Slag Brothers, Big Gruesome, Private Meekly, Clyde, and Morocco Mole. He also did some voices on ''WesternAnimation/TeenageMutantNinjaTurtles1987'' such as Leatherhead the mutant alligator and some additional characters. He also did the voices of Don Karnage and Louie in Disney's ''WesternAnimation/TaleSpin''. Cummings has also provided voices for video games, television commercials, and movie trailers, and is the current official announcer for Kids' WB!, as well as the official spokesperson for the current Cheez-It commercials. Recently, he returned to his role as Taz on ''Bah, Humduck! A WesternAnimation/LooneyTunes Christmas''.

In the world of video games, Cummings has done the voice of Minsc of ''VideoGame/BaldursGate''[=/=]''Baldur's Gate 2: Shadows of Amn'' and Drizzt Do'Urden in the first ''VideoGame/BaldursGateDarkAlliance'' game. He is also prominently displayed in the credits of ''Franchise/KingdomHearts'' as Pooh, Tigger, and Pete. Cummings provided the voices for "Bad Mr. Frosty", "Hougan", and "Sumo Santa" in ''ClayFighter 63 1/3''. He also voices "Sarge" and the other soldiers in the ''VideoGame/ArmyMen'' games. In ''VideoGame/{{Ys}} Book I and II'' for the Turbografx -16 CD system, he is credited as voicing "Dalles", and he provided voices for minor characters in ''VideoGame/GabrielKnight: Sins of the Fathers''. He played several characters in the little-known ''VideoGame/{{Toonstruck}}''. He also provided three of four of the voices of the main antagonist of ''VideoGame/{{Fallout 1}}'', The Master. He also provides the voice of the Terror Mask in the 2010 {{Splatterhouse}} remake for the Xbox 360 and PS3. He did a significant amount of voice work for [[VideoGame/TheElderScrollsVSkyrim the most recent Elder Scrolls title]]; most "[[GrumpyOldMan curmudgeonly]]" voices in the game are provided by him. Most recently he's protrayed [[TheObiWan Lorewalker Cho]] in WorldOfWarcraft. In addition, Cummings narrates the current Epcot fireworks show at [[DisneyThemeParks Walt Disney World]], ''[=IllumiNations=]: Reflections of Earth''.

Cummings has a notable cameo in ''ComicBookTheMovie'' as an inebriated party-goer. This is one of very few live-action appearances. The movie stars many other voice actors, including TomKenny, Creator/MauriceLaMarche, Creator/BillyWest and Creator/MarkHamill.

Cummings even did make some vocal performances using his voice at normal pitch for some younger looking characters like Witterquick from ''WesternAnimation/{{Visionaries}}: Knights of the Magical Light'' and Buddy Boar from ''WesternAnimation/TazMania''.

!!Tropes associated with Jim Cummings include:

* FriendToAllChildren: Takes time out to phone kids in hospital in character as Franchise/WinnieThePooh.
* GutturalGrowler: His most common role.
* LargeHam: '''[[VideoGame/BaldursGate MINSC]]'''. And believe it or not, that's not the only ham Cummings has.
* ManOfAThousandVoices: While his GutturalGrowler voice is his most well-known, he has quite the vocal range. [[VideoGame/{{Fallout}} The Master]] is a great example of this, where the same character has four distince voices: a normal speaking voice, his afformentioned Guttural Growler, a computerized voice, and a female voice. Three of those voices are from Cummings.
* MassiveMultiplayerCrossover: In an appearance at a [[FanConvention ConnectiCon 2013]], he [[http://www.youtube.com/watch?feature=player_embedded&v=fSvkgign8mQ did a reading of Darth Vader's lines]] from ''Franchise/StarWars'': ''Film/ANewHope'' in character(s) as Disney/WinnieThePooh and WesternAnimation/DarkwingDuck. He promptly [[SugarWiki/FunnyMoments brought down the house]] when he [[{{Improv}} ad-libbed]]:
--> "She must have hidden the plans in the escape pod... Oh bother!"
** He then afterwards did a rendition of ''Film/GoneWithTheWind'' as [[Disney/ThePrincessAndTheFrog Ray the Firefly]] and Disney/WinnieThePooh.
--> "Frankly my dear... I don't give a heffalump."
* NoIndoorVoice: As Tigger, Norton Nimnul and Minsc.
* PlayingAgainstType: In ''VideoGame/GrandTheftAutoV'' as a foul mouthed police officer, gun clerk, and radio announcer.
** Before that, he played the incredibly foulmouthed Terror Mask from the 2010 ''VideoGame/Splatterhouse'' remake.
