I had a vague recollection the other day of a film that I watched as a kid and was wondering what it was.
I would guess that must of been made in the seventies, could of had Roger Moore in or Micheal Caine but not sure.
The plot is about a diamond robbery and involves the use of cockroaches to sneak into a vault full of diamonds. The diamonds are then extracted via the ventilation system through a vacuum cleaner. I seemed to remember there is a guy who is locked in the vault???

Any ideas

The two actors you mention was in a caper movie caled Bullseye!

i remembered a film with diamonds, a cockroach, and especially our very own James Mason, being left inside a bank of somekind. I think 11 Harrowhouse (1974) is what you're looking for.
