The movie Hot Tub Time Machine has stars like John Cusack, Craig Robinson, and Rob Corddry all "kicking some past" when they travel back to the 1980s, it's an actor with cinematic time travel experience who is really heating up the search box. Who is this mystery man?

Hello, McFly, anybody home? George McFly himself, Crispin Glover, has gone back in time in this lazily scripted, but undeniably funny time-travel comedy that finds four losers - three 40-something buddies and a 20-year-old who lives in his uncle’s basement submerged in “Second Life” - hurtling back to the Reagan era via the titular time machine.
