Candace Cameron Bure
Movie count: 18
If you feel like every time you turn on the Hallmark channel, Bure is on, there's a good reason for that. The Full House star has been in a whopping nine standalone Hallmark films, as well as the Aurora Teagarden series of mystery movies. She's made at least one per year since 2011 and been especially prolific in the past few years. Bure's contributions to the channel haven't just been limited to programming: she's also been credited as executive producer on over a dozen of her movies.
