It's been said many times over, but those that get to market the Deadpool movies must be having themselves a blast. Basically taking traditional marketing ideas and giving them a re-imagination. Things like the Valentine's Day-inspired ad for the first movie a music video with Celine Dion, taking over the cover art of popular movies, and now delivering a late night monologue. Deadpool (Ryan Reynolds) stopped by The Late Show w/Stephen Colbert to talk to the host and, more importantly, deliver a monologue.
And of course we get ourselves a Thanos joke at the end.
