Alan Tudyk commented on Death at a Funeral in an interview for a broadway play. See the full interview here
But the one that I'm really excited about I did last summer in London, Frank Oz directed, and it's called Death at a Funeral, and it's a farce. I am anxious to see how it does because Frank cast whoever he wanted, and they allowed him to cast whoever he wanted, and what ended up happening was you've got a cast of actors who are not necessarily name actors that people go "oh I'm going to go see the new Russell Crow movie". There isn't this star attached to it that gives it that kind of box office heft, it's just actors doing this very funny script. To the audiences they've shown it to, it's gone really well. It was just at the HBO Aspen Comedy Festival and it won the audience award, which was great, but I play a guy who's an Englishman and it takes place at a funeral, and he's a very sort of nervous fellow and on the way, it's my fiancée's uncle who's passed, and we're on the way and I don't want to go, the father hates me, and it's awful, the whole thing's just stressful. And we stop by to pick up her brother, and he's a drug dealer, we don't know that he's just made a drug deal over the phone, and he's a pharmacy student. And he's like, "listen, this is the best stuff you've ever take" because it's acid mixed with catamine mixed with speed, and he puts them in a valium bottle. We pick him up to go, he's dressed, and my fiancée offers me a valium to take to relax me because I am so upset, and I take valium and for the first ten minutes of the movie I am fairly normal, and then for the rest of the movie I am out of my mind.
