10. Heath Ledger Licked His Lips To Fix His Facial Prosthetics - The Dark Knight
In order to play The Joker, Heath Ledger had to don not only grungy facepaint but also prosthetics for the character's ambiguously-received facial scars.
However, this presented an issue during shooting, as due to the prosthetics being glued across Ledger's mouth and lips, they naturally began to become loosened during extended takes where Ledger had to speak.
But ingeniously, Ledger came up with his own novel solution to the problem - to have The Joker frequently lick his lips, which in addition to ensuring the prosthetic stayed glued to his face, looked sublimely creepy.
Considering it's one of the character's most prominent physical tics, in an Oscar-winning performance no less, it's shocking that it was ultimately a practical concern rather than a purely artistic one.
