There are many celebrities who have filmed cameo appearances and acted their socks off, but their scenes ultimately ended being cut. Even though, their cameos were cut from the movie, the social media and the Internet have made them available for everyone to see. Below are some of the celebrities' cameos which were deleted from the movie.

Harrison Ford in "E.T."

Ford was cast as Elliot's principal, while his ex-wife Melissa Mathison also had a small part as a nurse in "E.T." Reportedly, director Steven Spielberg had to delete Ford's scene because he didn't want other faces of adults, except Elliot's mother, to show until the end of the movie.
