Though Hail Caesar! star Alden Ehrenreich was officially cast to play a young version of Han Solo in an upcoming Star Wars movie [Ed. note: He is genuinely incredible in Hail Caesar!, so good for him], the team at Lucasfilm auditioned literally thousands of actors for the role. Some of them apparently* included Melissa McCarthy, Curtis "50 Cent" Jackson, and Adam Sandler.
It's honestly just worth it for Jeff Goldblum.
*Fictionally for the purposes of comedy.
