Demi Moore – Shaved Head & Intense Military Fitness Regime
The wonderful Demi Moore worked hard to get into the character because of her role as Lieutenant Jordan O’Neil in G.I. Jane. She adopted a grueling fitness regime that actually saw Demi go through harsh training in the military. She would wake up at 4 a.m. to go jogging alongside Stephen Helvenston, a NAVY Seal instructor, working with trainer Gregory Jouron-Roche.

Mariah Carey – Hair Dye, No Skincare, Makeup Or Hair Removal Routine
Diva Mariah Carey likes to look perfect, and for years she has nurtured her magnificent looks. She did, however, give up everything for a role in the film Precious. She didn’t just change her hair color from blonde to darkish brown for the role; she also didn’t wear any makeup. Carey later revealed that her biggest challenge was playing in a movie with no makeup on, but she had to follow the director’s directions after all.
