When an actor really nails a role, making us believe the character they're playing truly exists, audiences don't really think about how the actor prepared for the role, they just enjoy the show.
But even great actors need a little help now and again to get really in touch with the role, and for some method acting means they're actually drunk as a skunk while playing the role.
It makes sense to drink up before playing a character like Tyler Durden in Fight Club or Willie Stokes in Bad Santa, but it's surprising to find out Daniel Radcliffe struggled with alcoholism while playing Harry Potter.
I bet the booze made everything seem that much more "magical" during filming!
But Daniel is in good company, because some of the most iconic performances of all time were delivered by drunk actors.
Martin Sheen got nice and saucy before "acting" out during the opening scene of Apocalypse Now, and his drunken fit was so compelling to watch Coppola kept the cameras rolling even after Sheen sliced open his hand when he punched the mirror.
