Kaitlin Olsonis becoming one of the biggest TV stars, especially after she pulled double duty duringthe second week of January 2025 when she starred in new episodes of two big shows.After graduating with a bachelor’s degree in theater from the University of Oregon, Olson moved to Los Angeles to pursue an acting career in the late 1990s. At first, the actress did sketchy comedy and booked small parts in TV series here and there. However, Olson’s breakout came in 2005 when she beganplaying Dee Reynolds inIt’s Always Sunny in Philadelphia.

Olson has starred in various other substantial projectsover the years, ranging from her first TV appearance as Cheryl Hines' sister inCurb Your Enthusiasmto 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 (forFlipped) and two for Outstanding Guest Actress in a Comedy Series (forHacks). Many will always see Olson as Dee, though. But, her performance in a new network procedural drama might change how some view Olson.

Olson Is Great In Both

Part of what makes Kaitlin Olson’s network TV takeover so fun is that the character she plays in theIt’s Always Sunny/Abbott Elementarycrossover andOlson’s role inHigh Potentialcompletely 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.
