'How I Met Your Dad's Greta Gerwig Isn't the First Indie Star to Shake Up Primetime TV

Try using the arrow keys

Rarely does any CBS show elicit controversy, but when it was announced on Tuesday that actress Greta Gerwig would be starring in How I Met Your Dad, a spinoff of hit How I Met Your Mother, it was as if the network had decided to cancel HIMYM altogether with a quick "spoiler alert: they met." The casting of Gerwig, an actress best known for indie movies like Greenberg and Frances Ha , caused an uproar with fans and critics, with many saying that a star of low-budget films was an odd, if not bad, choice for a leading role in a network series. Opponents argued that HIMYD would be a step down for the Golden Globe-nominated Gerwig, or that the show would be better off with a TV actress as the lead.

Yet while Gerwig's casting is certainly surprising, it might not be so bad. In fact, it has the potential to be great — just ask these 6 indie actors who made the crossover to mainstream TV, shaking up the system and making television way more interesting.
