The American Pie actress plays a bridesmaid in the wedding comedy, with Noel - who also co-wrote the script - playing the best man.
"I'm a huge fan of Noel's, I think he's just unbelievably talented and he's such a special force to be reckoned with," Mena said.
"I hope to work with him many more times in the future. As the American I guess!... He's always got three or four things in the works. We talked about it and I would really love that if it was something I liked."
Mena admitted she struggled to get the lingo in some of filmmaker Noel's gritty movies, which include Kidulthood and 188.8.131.52.
"With his previous films there were some times where I probably had to try and figure out what was said, the accent was so thick," she confessed.
"But I love British comedies. I love that type of humour, so it was great to be a part of. It is very particular but it's very witty, very smart."
