You might expect an A-list movie star like Joseph Gordon-Levitt to wear a fancy suit on the red carpet, but when it came time for him to attend the world premiere of Star Wars: The Force Awakens in Hollywood on Monday, The Night Before actor [1] arrived in a DIY [2] Yoda costume. Everyone knows Joseph isn't afraid of getting really into character [3], and his Yoda look was no different. Complete with a white terry cloth robe, Grinch pajama bottoms, a beanie with pointy ears, and a face full of green paint, he went full-on fanboy, and he wasn't the only one. Rainn Wilson [4] and his son, Walter, also went to the premiere in costume, donning "chubby Jedi" and Boba Fett getups. Keep scrolling to see more photos of the diehard fans!
