Which Ride or Die producer is the sister of filmmaker Andy Muschietti?

Barbara Muschietti is the producer and filmmaker who is Andy Muschietti’s sister.

The Argentine siblings have repeatedly collaborated on projects that Andy directs and Barbara produces. Their partnership became especially visible with Mama, which grew from Andy’s short film into the 2013 feature, and with the two-part adaptation of Stephen King’s It. Barbara also produced The Flash, directed by Andy for DC.

Barbara’s producing role is substantial rather than merely familial. She has helped develop projects, assemble creative teams and guide productions through the studio system. The siblings also formed the production company Double Dream, continuing their shared approach to genre filmmaking and large-scale adaptations.

A common mix-up is reversing their jobs or assuming Barbara is the director because the two often appear together in publicity. Andy is primarily known as a director and screenwriter, while Barbara is primarily known as a producer. Their later collaboration on It: Welcome to Derry continued the partnership that began with their earlier horror work.
