O'Toole and McKean were friends since the late '70s, often running into each other at parties hosted by Rob Reiner and Ed Begley Jr. Their romance only started after filming their 1998 TV movie Final Justice, which they recalled in a 2018 video for TheaterMania. The Smallville actress remembered McKean calling her one night after he finished watching ER while she was in bed with her sick kids (she shares two daughters with ex-husband Bill Geisslinger).

I said, 'I really, really want to talk to you but Anna's so sick. Could we talk tomorrow?' He said, 'Yea, I'll call you tomorrow.' I thought, he's never going to call me tomorrow. But I put the phone down and I went into the bathroom and jumped up and down in silent screaming." The couple ended up having their first date at a UCLA show, where Bob Dylan, Joni Mitchell, and Van Morrison performed, after she helped him shop for a pair of boots, which he still owns today. "I would have married him that day," O'Toole said.
