Okay, where do I even start with Galaxy Quest? It's like every sci-fi nerd's dream, space, time and Alan Rickman all rolled into one. Whilst at a convention the aging cast of well-known, now defunct show Galaxy Quest start to slowly realise everything they acted is actually real when an alien race needs their help. Why it should be a stoner film: Epically cheesy one-liners and spoof-filled action complete dodgy deep space special effects and costumes make for a funny watch. The deluded cast member's backstories will also give you something to chew over if you're looking for a thoughtful film and a heart-warming we-did-it end will leave you feeling all fuzzy inside. Even if you're not into sci-fi, this is still worth a try. Pretty light on the technical aspects, this film speaks to seasoned nerds and geeks as well as the occasional sci-fi fan. Highly underrated and utterly quotable, be prepared for some deep conversations about the perception of reality, maan. Never give up, never surrender! Memorable Line: "I'm not even supposed to be here. I'm just 'Crewman Number Six.' I'm expendable. I'm the guy in the episode who dies to prove how serious the situation is. I've gotta get outta here!" A special nod goes to Mathesar played by Enrico Colantoni, who will crack you up with a look alone, I guarantee.
