Karen Gillan first came to prominence playing Amy Pond during two seasons on Dr. Who. Then she was cast as Nebula in Guardians of the Galaxy Vol. 2 and her career went into overdrive. She'll be reprising her signature role in Thor: Love and Thunder and in Volume 3 of Guardians next year. Meanwhile, you can see her play opposite herself in the science-fiction feature Dual, now playing in theaters, and in Judd Apatow's The Bubble on Netflix. Leonard and Jessie are suckers for anyone with a Scottish accent, but Karen ups the ante with her outgoing personality and upbeat approach to her burgeoning career.
