Catherine O'Hara revealed that she had "such a crush" on  her Home Alone co-star John Candy, who died in 1994.

During an exclusive interview with PEOPLE magazine, Catherine shared that John's kind and generous personality attracted her when they worked together in Second City Television  and later on the spin-off show SCTV, which ran  from 1976 to 1984.

The Argylle actress said,  "He was just as lovely as you want him to be."

 Catherine also clarified that her feelings were one-sided, as John was already in a relationship with his wife Rosemary, whom he remained married to until his passing.

The Beetlejuice star explained, "I wouldn’t claim he was interested in me that way, but he was always really lovely to me in Second City Theater."

Catherine also discussed how John played a significant role in enhancing her skills, after she joined the SCTV cast in the 1970s.

"He would always be willing to do an improv with me after the show. You do a show and then you do improvs after the show," Catherine added.

The Nightmare Before Christmas star told, "That's how you build the next show at Second City Theater. And he was always willing to try any idea."

"You’d be on the street with him, in a mall, and somebody would come up and just want to do a comedy bit with him, and he would always pick up on it right away and give something back and see their eyes light up, like, oh, I’m doing a bit with John Candy," she added.
