Film buffs know the veteran character actor Seymour Cassel as a frequent player in movies directed by John Cassavetes and Wes Anderson. (Cassel played Max Fischer’s dad in Rushmore and Royal Tenenbaum’s fellow elevator operator in The Royal Tenenbaums.) When Slash was growing up in Los Angeles, though, Cassel was just his buddy Matt’s dad.
Even as a teenager, Saul Hudson had a lot of frenetic energy, and one day he was zipping from one room to another at a party at the Cassels’ house. The actor gently ribbed Hudson’s constant motion by asking, “Hey, Slash, where ya going? Where ya going, Slash? Huh?” The nickname stuck.
