Inspector Spacetime
Doctor, schmoctor. The real low-budget British sci-fi hero is Inspector Spacetime, a space traveler who can also travel through time. You need a bowler hat, a light-colored trench coat (or bathrobe, if that's what's at hand,) an ascot, a British phone booth and a faithful compatriot named Constable Reggie, all dressed up in an English Bobby uniform. That officially earns as a "cool cool cool."
