Anything from Mischief Theatre! They have their "Peter Pan Goes Wrong" for free on youtube atm.

Guest House Paradiso.

Batshit insane English humor. Got to love the style, but if you do, it's fantastic.

I really enjoyed 'Mindhorn'

If you enjoy UK comedy stuff

Cold Pursuit

I saw it in theatres and I remember people weren’t laughing and some were walking out because they were bored. I can guarantee that all of them saw Liam Neeson was the lead and were expecting another action packed Taken type movie. What we got instead was a movie reminiscent of Fargo or The Big Lebowski. It’s absolutely hilarious, I’ve watched it many times and I’ve shown friends this one and they’ve all loved it. Highly recommend!

Harold and Maude

I feel like not enough people have seen "Secondhand Lions".

Five Year Engagement. Mediocre reviews, but a really grounded and funny story.

The Do-Over. Yes I can’t stand Adam Sandler either but it’s such a fun movie.
