Boss Nass, the Gungan head honcho from The Phantom Menace. His booming voice and seizure-like expressions of displeasure make him more expressive than most of the human cast. The character was written as a strict, xenophobic no-nonsense ruler with little patience, who eventually had a change of heart when he realizes he's misjudged the race he despises, and becomes friendly and joyful. Blessed's performance changed the characterization.
Every character that Alan Hale Sr. did. His son Alan Hale Jr. did this as well early in his career. But as he aged he was cast more and more as a villain. Which is why he took the role of the Skipper in Gilligan's Island , he was tired of playing bad guys.
You could argue that El Indio from For a Few Dollars More is a deconstruction of this trope. He laughs all the time, hugs his friends a lot, is enthusiastic and boisterous and runs a band of plucky outlaws out to rob an impenetrable bank against all the odds — but he's a depraved child-murdering, stalking rapist and his band are all implied to be similarly bad. His happy laughing face gets on his "Wanted!" Poster, but he also has a much more evil, violent side to him which causes him to turn on his own men. Lastly, his good moods seem almost maniacal, and are probably induced with drugs.
For Your Eyes Only and Colombo, arguably a thinner version of the character. Played by Topol.
Antaeus the bully bandit from Hercules Unchained, featured in MST3K. At one point Crow even wishes that he was on the heroes' side, since he seemed a lot more fun than the real hero, Hercules (who seemed to spend most of the movie either sleeping or acting like a total crab).
Kingdom of Heaven: Liam Neeson's character, the Baron of Ibelin, who's a knight. He fights fiercely, even if he gets wounded (as he remarks himself: "I once fought two days with an arrow through my testicle!"). He also learns his son Balian to fight as well, and knights him.
Underground has the main characters, Serbian WW2 gunrunners Marko and Blacky. They love a good scrap and are always partying as hard as possible. In one scene, Marko stumbles across a brawl started by Blacky, hands his personal brass band a tip to play some fast-tempo music, and throws himself into the fray while dancing to the beat.
Smashley despite having only a handful of lines, is played with utter Large Ham aplomb by director Barrymore and steals every scene she's in.
Mace Windu, the number two Jedi on the Council (who first appeared in The Phantom Menace) qualified. He loved to fight, and given the tempting nature of the Dark Side, this was a dangerous trait for a Jedi to have; as a result, he studied favored Form VII (also known as Juyo or Vaapad) a very difficult and hard to use school of swordplay, that allowed near-unmatched mental discipline and lightsaber control. His concentration was such that he was even able to use certain Dark Side techniques, like Force Crush, without succumbing to the temptation. (However, he was clearly the exception, not the rule.)
Darius Kincaid in The Hitman's Bodyguard. Played by Samuel L. Jackson in full Large Ham mode, Kincaid's exuberant joie de vivre shines through whether he's killing a bunch of bad guys, trolling his bodyguard, or making friends with a busload of singing nuns.
Blackbeard is portrayed this way in Anne of the Indies: carousing, consuming huge quantities of food and booze, and firing his pistols into the ceiling when he wants silence.
M'Baku in Black Panther (2018), a very large man with a very large presence, is both a fierce warrior and a jovial Troll who laughs at his own jokes.
"He had married twenty-eight times, had been wounded thirteen times, and in the battles he provoked had seen all his tribesmen hurt, and most of his relation slain. He himself had killed seventy-five men, all Arabs, by his own hand in battle... He saw life as a saga, and all events in it were significant, and all personages in contact with him heroic. His mind was stored with tales of old raids, and epic poems of fights. He had no control over his lips, and was therefore terrible to his own interest, and hurt his friends continually. He spoke of himself in the third person and was so sure of his fame that he loved to shout out stories against himself. At times he seemed taken by a demon of mischief: and yet with all this he was really modest, as simple as a child, direct, honest, kind-hearted, and warmly loved even by those to whom he was most embarrassing - his friends.
