playing Dee Reynolds in It's Always Sunny in Philadelphia.

Olson has starred in various other substantial projects over the years, ranging from her first TV appearance as Cheryl Hines' sister in Curb Your Enthusiasm to voicing a whale shark in a billion-dollar Pixar film. She has also been nominated for three Emmy Awards — one for Outstanding Actress in a Short Form Comedy or Drama Series (for Flipped) and two for Outstanding Guest Actress in a Comedy Series (for Hacks). Many will always see Olson as Dee, though. But, her performance in a new network procedural drama might change how some view Olson.

Kaitlin Olson Returns in High Potential & It's Always Sunny In Philadelphia Episodes This Week

Olson Cameos With Her It's Always Sunny Costars In Abbott Elementary

The week of January 6, 2025, is the week of Kaitlin Olson on network TV. First, following a two-month hiatus, Olson reprised her leading role as Morgan Gillory in High Potential season 1, episode 8, on Tuesday, January 7. The new ABC crime drama series has been a ratings and critical hit since its premiere in September 2024. High Potential's midseason return continued breaking records, suggesting a renewal is inevitable (and Olson won't be leaving our screens anytime soon).

One day after High Potential, season 1, episode 8, Olson made a cameo as Dee alongside her It's Always Sunny in Philadelphia castmates in the show's crossover with the ABC sitcom Abbott Elementary. The first part of the highly anticipated event premiered on Wednesday, January 8. To no one's surprise, the It's Always Sunny and Abbott Elementary crossover was well-received, continuing Olson's dominance on network TV.

High Potential's Morgan & It's Always Sunny In Philadelphia's Dee Couldn't Be Any More Different

Olson Is Great In Both

Part of what makes Kaitlin Olson's network TV takeover so fun is that the character she plays in the It's Always Sunny/Abbott Elementary crossover and Olson's role in High Potential completely clash. Dee is nothing like Morgan, and Morgan's personality is a far cry from Dee's. Dee is egotistical, shallow, desperate for attention, and, of course, hilarious. Meanwhile, Morgan is a genius, bold, caring, unconventional, and stubborn.

Part 2 of the Abbott Elementary and It's Always Sunny in Philadelphia crossover (an episode in It's Always Sunny in Philadelphia season 17) will premiere in mid-2025, according to TODAY.

Since Dee and Morgan are so different, Kaitlin Olson's ability to convincingly play them both is impressive, to say the least. The contrasting characters highlight Olson's acting skills, making her talent all the more obvious when she stars as Morgan in High Potential one night and Dee in the Abbott Elementary and It's Always Sunny crossover the next.
