TIL John Astin, the father of Sean Astin (Samwise Gamgee), auditioned for the part of Gandalf, & had previously starred in Peter Jackson's horror comedy 'The Frighteners'
John Aston married Sean's mother Patty Duke when Sean was less than two years old. He grew up believing that Dezi Arnaz, Jr. (as in, the son of Lucille Ball and Dezi Arnaz!) was his biological father (though he found out later this wasn't the case). He's basically the ultimate nepo baby.
