6. Keanu Reeves Lost Weight For The Pod Sequence
It's far from uncommon for an actor to either put on or lose weight for a role in a film - from Robert de Niro to Christian Bale, plenty of pounds have been added or shed in the name of enhancing a performance. If anything it can seem like a cynical ploy designed to garner Oscar nominations, showing just how much they're willing to struggle for their art. Keanu Reeves probably wasn't thinking about winning any awards for his acting whilst filming The Matrix, but he certainly deserves credit for shedding some weight for the scene in which he is pulled from the Matrix and awakens in the pod. In an interview he revealed how he wanted to appear as emaciated as possible, and while the change is certainly a subtle transformation, it's clear that he's not as athletic as during the fight sequences.
