[Suggest] Meantime (1984) - a 19 year old Gary Oldman and Tim Roth play two skinheads in a comedy drama about their bleak and pointless lives. Directed by Mike Leigh.

Based on the description, I totally thought it was talking about Rozencrantz and Guildenstern Are Dead (which is also good, watch it).

Another great early Gary Oldman movie is Prick Up Your Ears (1987).

I had no idea it was supposed to be a comedy, it's really bleak!
