Movie transformations are often among the most impressive achievements in filmmaking. Through prosthetics, wigs, body suits, and detailed makeup work, actors can completely disappear into their roles, becoming characters that look nothing like themselves. These transformations help bring fantasy worlds, historical figures, monsters, and superheroes to life while making performances feel more believable and immersive.

However, many of these transformations come at a cost. Before cameras even start rolling, actors sometimes spend three, four, or even six hours sitting in makeup chairs while teams of artists carefully apply prosthetics by hand. Some stars have described the process as exhausting, uncomfortable, and mentally challenging, while others have said they would never willingly repeat it. Despite the long hours, these remarkable transformations have produced some of cinema’s most unforgettable characters and remain shining examples of what practical makeup effects can achieve.

Meet the Writer

Matt has spent over the last 8 years as both a writer and editor, working in Seattle and Brooklyn, where he is now based. He loves escaping the tirelessly fast pace of the “Mad Apple” that is NYC by taking walks and runs through parks where he’s able to catch up on the latest tea about society from the city’s ever chatty, always hungry, occasionally maniacal, pigeons. They always have a lot to say. When he’s not taking his urban nature strolls, or dutifully combing the deepest rabbit holes of the internet to find the content that’s worth sinking your mind’s teeth into, he’s likely holed up at a dark-lit dive bar with a new book and/or some friends, or just as easily he could be on the hunt for the next addition to his steadily growing plant family.

These days Matt’s caught up in trying to provide folks as many vivid glimpses into the days long since passed as he can, through fun and engaging collections of hand-picked vintage photos.
