10 Actors Who Did Not Take Credit For Big Movie Roles

Christopher Nolan's abhorrently overlong, mostly confusing yet strikingly beautiful film Interstellar caused a rift among fans of the director's oeuvre. His biggest defenders still shout about its scientific accuracy (still widely debated by celebrity scientists like Neil DeGrasse Tyson), its detractors point to the fact that, sometimes, there's no way to make science interesting if one isn't already invested.

While searching for a habitable planet as the earth suffers its final dust bowl, farmer-turned-somehow-astronaut Matthew McConaughey and Anne Hathaway run across a previous failed expedition. After the last survivor of said expedition is thawed out, audiences were surprised to see the familiar face of Matt Damon - who almost instantly succumbs to space madness and nearly kills the whole crew.

One can't help but wonder, watching them back to back (should you have 14 hours to kill), how The Martian would have played out had it been the same character. No reason was given by the studio or Damon, and save for a Variety report that mentioned he played an "unspecifed role". It wouldn't be the last time, as Damon appeared a few years later in Unsane, Deadpool 2 and Thor: Ragnarok, all without billling.
