Catherine O'Hara is terrifically hilarious. Definitely one of the all-time great comedy actresses.

PS: I do also love Andrea Martin.

She was fabulous in her many SCTV roles and that as it was almost just the beginning. She was also on Wayne and Shuster in some of their later work ( obviously not in their 50s TV show). Two points.

1. She, despite her double greatness, used the SCTV/Saturday Night Live buddy connection system to get many parts. What would her career have been like if she only had been connected with the SCTV gang till 1984 and then did all work with only others not in that system.
2. There was a toss up between her and also SCTV actress Andrea Martin ( can't rightly use the word "fellow") as to who was better. Definitely O'Hara was. Not only way more attractive but even more talented. Martin really bombed in a movie she did around 1986 with Robin Williams see my postings.

She didn't bomb, the movie did. Big difference.

Gen, the talent of the SCTV performers was demonstrated in the opening credits of the series.
