Few things will attract audiences to a movie quite like a cast jam-packed with talented and beloved actors, but as these films all categorically proved, an all-timer roster isn't everything.
There are few things sadder in Hollywood than seeing a massive ensemble cast squandered on underwhelming material undeserving of their talents, and that's absolutely the case with each of these 10 films.
Now, this isn't to say that all of these movies are irredeemably awful trainwrecks - though a few of them certainly are - but simply that they failed to make inspired use of the astounding personnel at their disposal.
Despite having Oscar-winning legends and arguably some of the greatest actors of all time on-hand, these films failed to rise above mediocrity, and arguably worse than being outright bad, some were quickly forgotten by mass audiences.
The lesson here? When a film's marketing leans hard on just how impossibly stacked with great actors it is without drawing much attention to the story, there's probably a calculated reason for it.
These 10 movies left their casts desperately trying to elevate material that flatly didn't deserve them...
10. Movie 43
Not all movies on this list are awful, but Movie 43 certainly is, and to that end is surely the most egregious example of a ludicrously talented cast being squandered on grossly un-worthy material.
The primary reason that the Peter Farrelly-produced film was able to secure a bevy of veritable Hollywood A-listers? It's an anthology movie, meaning the actors involved only required a few days of participation as suited their schedules.
For starters, Movie 43 counts among its massive ensemble cast four winners of the Best Actress Oscar - Halle Berry, Kate Winslet, Emma Stone, and Julianne Moore - not to mention Oscar nominees Terrence Howard, Hugh Jackman, Uma Thurman, and Naomi Watts.
Beyond that, there are appearances from a glut of name performers: Kristen Bell, Gerard Butler, Seth MacFarlane, Leslie Bibb, Kate Bosworth, Josh Duhamel, Anna Faris, Richard Gere, Chris Pratt, Johnny Knoxville, Chloë Grace Moretz, Liev Schreiber, Seann William Scott, Jason Sudeikis, Bob Odenkirk, Dennis Quaid, Greg Kinnear, and Anton Yelchin.
Hilariously, Gere and other actors reportedly attempted to get out of the project before shooting, while George Clooney was approached to appear and flat-out said no.
Producer Charles B. Wessler used his industry connections to persuade many of the actors to shoot their brief scenes, and unsurprisingly, Movie 43 went on to be panned by critics, while receiving numerous Razzie nominations, including the entire cast for "Worst Screen Combo."
Any filmmaker that convinced Hugh Jackman to stick a pair of plastic testicles to his chin has to earn some sort of begrudging respect, though.
