A blockbuster movie role can elevate an actor's career and even make them overnight stars if it's successful enough, yet for most on-the-job actors they're simply a handsome payday which perhaps allows them time to pursue more "artistic," lower-paying projects.
And though blockbusters aren't generally made to be forgotten, sometimes a name actor's role in a tentpole film is so bizarrely slight that you might forget they were ever in it at all.
These 10 actors, whether rising stars at the time or firmly established Hollywood royalty, all showed up in some huge movies, only for their presence to be quickly forgotten in the months and years that followed.
In some cases it's simply a matter of the actor's subsequent work overshadowing this smaller supporting role, while in others it's clear the actor in question was just collecting a fat paycheck for as little work as possible.
Either way, all but the most hardcore fans of these actors will have long forgotten that they appeared in these massive films, only to quickly find themselves lost amid the action, the CGI, and the huge ensemble casts...
10. Rami Malek - The Twilight Saga: Breaking Dawn – Part 2
There's no mistaking the veritable pop-culture phenom that was the Twilight franchise, a series which, while laughable by any "serious" filmmaking metric, nevertheless boosted the careers of numerous rising actors beyond Robert Pattinson and Kristen Stewart.
Even so, does anyone remember that Academy Award winner Rami Malek had a role in the series' final film, Breaking Dawn - Part 2?
Malek plays Benjamin, a member of the Egyptian coven who possesses the ability to manipulate the Earth's elements.
He doesn't get much to do during his brief screen time, though does memorably use his powers to create a giant sinkhole during the final battle - which, of course, turns out to be a premonition of a fight which never takes place.
Thankfully Malek only had to wait a few more years for his big break with Mr. Robot, which catapulted him into the stratosphere and led to him taking the career-defining, Oscar-winning role of Freddie Mercury in Bohemian Rhapsody.
As terrible as Breaking Dawn - Part 2 is, Malek shouldn't be embarrassed to be a part of what was clearly a career stepping stone for him.
