Pride and Prejudice and Zombies. Jane Austen etiquette, manners, humour, and loping heads off zombies. What more do you want from a film 
Boat Trip. A man upsets his travel agent and, instead of a male/female singles cruise he gets booked onto a gay cruise. I'd watch this over and over just to see Roger Moore playing a gay SAS officer who, with his team, help to save the day. He plays it totally straight (no pun intended).
Rat Race. So many big names in this film. Whoopi Goldberg, Rowan Atkinson, John Cleese and many more. A glorious farce. Hysterically funny.
