Voluntary Shapeshifting / Live-Action Films

• Professor Browne in Bedknobs and Broomsticks pulls this off when he uses Miss Price's spell to turn himself into a rabbit in order to gain access to the castle the Nazis have imprisoned Miss Price and the children.
• The title ghost from Beetlejuice.
• Bit: Vlad can turn into animals like rats, and also mist.
• The girls from The Craft can make themselves look like other people using disguise magic.
• An important plot point in Detective Dee and the Mystery of the Phantom Flame hinges on a certain acupressure point that allows you to completely alter the shape of your face. For Chinese audiences, the impact is heightened by iconic character actor Richard Ng transforming into equally iconic character actor Teddy Robin. A Hollywood equivalent would be if Steve Buscemi ripped off a rubber mask to reveal himself as Christopher Walken.
• Vampires in film since Dracula (1931) starring Bela Lugosi. Its second sequel Son of Dracula was the first movie to actually show transformation sequences.
• Dungeons & Dragons: Honor Among Thieves: Doric is able to morph into seemingly any animal she wishes, though she defaults to the shape of an owlbear for combat.
• Carmen Electra plays a parody of Mystique in Epic Movie (2007). In one scene, Peter requests her to transform into increasingly bizarre forms to please his various fetishes: unibrows, giant butts, flabby arms, etc.
• In Eternal, Elizabeth's Right-Hand Attack Dog is actually her maid Irina, who can transform into a Rottweiler.
• The Golden Child. At one point, Sardo Numspa changes his form from a rat into his normal shape and back into a rat again.
• Near the end of Grandmother's Farm 2, we see the djinn change from human form to cat form.
• Due to Heath Ledger's death, a mechanism was written into The Imaginarium of Doctor Parnassus where dishonest people tended to have different faces than their real ones when transported into the imagination world. Fitting this trope, it's somewhat implied that Parnasus could use this beyond clothes, but chose not to so as to be properly recognized by the others. Played totally straight — in the fantasy if nowhere else — by the one that gave him the Imaginarium: no less than Satan himself.
• In Inception, Eames is a "forger", which means he can take on the appearance of other people when in a dream. Perhaps not a straight example of the trope as he can't do this in reality, but...
• It Came from Outer Space: The aliens can copy humans and their memories, but give themselves away through their awkward speech patterns and ability to stare into the sun without blinking.
• Jareth from Labyrinth can turn into an owl.
• Magic in the Water: According to legend, the monster Orky has evaded capture due to his ability to transform into anything, including a human.
• Loki from the Marvel Cinematic Universe can create illusions that mimic shapeshifting. He does so particularly often in Thor: The Dark World, in one scene even impersonating various other characters for fun. Also in Thor: Ragnarok, Thor tells a story from their childhood about Loki turning into a snake for a prank, which appears to be an example of actual shapeshifting, as Thor mentions picking the snake up — Loki's illusions are consistently intangible. However, this ability has never been displayed onscreen.
• Jim Carrey played The Mask in the movie with the help of groundbreaking makeup and animated effects.
• Freddy Krueger of the A Nightmare on Elm Street film series is a master shapeshifter through his dream powers. His favorite use of this is to impersonate his victims' loved ones or other related people so he can scar them emotionally before killing them, like appearing as a teenager's murdered brother in Freddy vs. Jason or as a girl's sexually abusive father in Freddy's Dead: The Final Nightmare.
• Once Upon a Time (2017): Bai Qian can turn into a nine-tailed fox and Ye Hua can turn into a dragon.
• In Pixels, Q*Bert turns out to be capable of changing into other game characters.
• Sky High (2005) has an interesting inversion with the character Magenta. She can change her shape at will, but only to the form of a guinea pig (with purple highlights, no less). Turns out to be rather useful (like the other lame powers in the movie), in a This Looks Like a Job for Aquaman scenario.
• Star Wars introduces this in Attack of the Clones with the bounty hunter Zam Wesell. Though bizzarely, she fails to ever actually use this power, even when it would obviously allow her to escape pursuit. Though this could be due to the fact that shapeshifting in public would be too obvious, and it seemed safer to just attack. The Expanded Universe indicates that there is a notable prejudice against changelings, as a result of their abilities.
  • An example from Star Wars: The Clone Wars is much more impressive, in which she is able to use her abilities to successfully impersonate two different Jedi, only being caught when Ashoka notices odd behavioral cues, as well as discovers the unconscious body of the person that the changeling is impersonating.
  • As Darths & Droids notes, the fact that changelings exist but are never otherwise used in the films is also a wasted Chekhov's Gun.
• Terminator:
  • Terminator 2: Judgment Day gives us the aforementioned T-1000. Capable of imitating almost anything it touches, but not replicating it, since it is made out of liquid metal. It's able to turn its limbs into various weapons such as knives or hooks. Complex machinery such as guns is a problem, because they have specific components such as chemical reactions and moving parts. It also often imitates people it's just killed in order to move around freely (its default appearance being a cop) or to get closer to its target. Due to its natural liquid form being able to reassemble at will, it is virtually indestructible by any means of conventional weaponry.
  • The T-X from Terminator 3: Rise of the Machines is a downplayed version of this. It's composed of liquid metal over a solid Terminator skeleton. Due to this it can't do quite as much reshaping as the entirely liquid metal T-1000, in exchange for having the hardware to do some things the T-1000 couldn't, but it can still alter its appearance and take on people's identities.
• The Djinn in Wishmaster can take on the form of others, but he has to use their faces for it. The Djinn in the fourth film does it without restriction at one point.
• X-Men Film Series:
  • Emma Silverfox in X-Men Origins: Wolverine, can transform her body into diamond, bullet proof skin.
  • Emma Frost in X-Men: First Class, can turn into a crystalline form of herself that is immune to psychic influence, but isn't immune to Erik's powers. There is debate/retcons/etc. over whether or not they're both versions of the Emma Frost.
  • The Mark X Sentinels in X-Men: Days of Future Past, in addition to an ice-form, can turn into a diamond-like form, which they do later on in the film just before chopping off Sunspot's arm and killing him. Considering one of the mutants experimented on to create them was Emma Frost, it makes perfect sense.
  • Mystique, just like in the comics, is a master shapeshifter. Wolverine is one of the only people who isn't fooled by her guises since she can't get quite get the scent right. The Mark X Sentinels' ability to shapeshift is the result of experiments performed on Mystique.
