Resident Evil: Apocalypse (2004)

Sienna was 29 when she was casted to play Jill Valentine in the movie Resident Evil 2004. Everyone was there (Milla Jovovich, Michelle Rodriguez, Boris Kodjoe, Colin Salmon, Sienna and at last you). You were casted to play a young intruder only to have escaped from the supposed "Umbrella Corporation". Everyone on set were friendly and funny with each other. Especially Sienna who was overprotective over you since being the only teen there.
