You have to be tough to join the Green Lantern Corps. Kilowog, the alien drill instructor, gives Hal Jordan his first lesson in GL-ology — the hard way — in this first clip from Green Lantern.

Duncan was on G4's Attack of the Show talking up his role voicing Kilowog, and he shared this clip in which Kilowog almost launches Hal Jordan into an artificial sun — just to show the weak Earthling what he's dealing with. [via Screenrant]
