Halloween Kills brought back a number of franchise OG's, including Dr. Loomis.

Donald Pleasance's performance as Dr. Loomis in Halloween is the stuff of horror legend, but he wasn't John Carpenter's first choice for the role.

In the original story treatment for Halloween H20, the sequel introduced Dr. Loomis' daughter, only to abruptly kill her off in the first act.

Rob Zombie's Halloween movies have their fans, but one character he just didn't do right by was Michael Myers' psychiatrist Dr. Sam Loomis.

At the end of Halloween 2 (1981), Dr. Loomis (Donald Pleasance) seemingly perishes in a fire alongside Michael Myers, only to return for Halloween 4.

Halloween and Psycho have more in common than being classic horror films: both have a character named Sam Loomis, and the connection might be deeper.
