Filming began in September 1932 and was scheduled for three weeks. Karloff's first day was spent shooting the Mummy's awakening from his sarcophagus. Make-up artist Jack Pierce had studied photos of Seti I's mummy to design Imhotep; however, Karloff looked nothing like the mummy of Seti I in the film, instead bearing a resemblance to the mummy of Ramesses III. Pierce began transforming Karloff at 11 a.m., applying cotton, collodion and spirit gum to his face; clay to his hair; and wrapping him in linen bandages treated with acid and burnt in an oven, finishing the job at 7 p.m. Karloff finished his scenes at 2 a.m., and another two hours were spent removing the make-up. Karloff found the removal of gum from his face painful, and overall found the day "the most trying ordeal I ever endured". Although the images of Karloff wrapped in bandages are the most iconic taken from the film, Karloff appears on screen in this make-up only for the opening vignette; the rest of the film sees him wearing less elaborate make-up.
