Actor and comedian Catherine O'Hara said she has so much fun making movies that receiving a star on  comes as a surprise to her.

"I hardly ever work. I forget that I work," O'Hara told Canada AM, "so this thing makes no sense."

"When I'm working, it's like 'Oh, I'm working so hard.' But when it's over, it's over and life goes on."

O'Hara says that she especially has fun when she is working with long-time friend and former SCTV colleague Eugene Levy. Levy will be hosting the Walk of Fame ceremony on Saturday when O'Hara will be inducted.

The two actors have worked together frequently in the past, including in a pair of movies directed by Christopher Guest, 'Best in Show' and 'For Your Consideration.' Guest and Levy collaborated on writing the mainly improvised scripts for both movies.

"It's just inspiring and you get to bring your own character to that story and all the dialogue," O'Hara said. "And sometimes...they can't help themselves and they'll think of some joke and they put that in for a character and it's just something to jump from."

The sense of fun and creativity O'Hara gets from working with scripts Levy has crafted extends to when the pair share screen time.

"Eugene and I tend to laugh mostly when we're dying," O'Hara said. "We're just flailing when neither of us are coming up with anything and one of us will be saying more than we need, just waiting for something good to come out, like 'Talk! Talk!'"

"You'll just catch the other person looking at you like 'You are dying so badly right now,' and we'll laugh. But when it's good when it's going well, you don't want to laugh because that kills the take and like you say, it will never happen again. And you do a few takes, you'll do one and...when you shoot those movies you roll, until the cameras rolled out."
