Lol, the drink was supplied. The worst part of doing the film in my opinion was all the drinking scenes were real, as we were experimenting with the American style of Method acting, compared with the British "System".
The montage part where you see me with a beer bong for a split second was real. It had 3 can's of Larger and 1 can of Cider in the pipe. I necked it in 15 seconds at 10.30am.
