Dont Worry Baby (2015) Struggling photographer Robert (John Magaro) and his philandering father Harry (Christopher McDonald) realize that they both had a one-night stand with the same woman, Sara-Beth, in the same week. Years later, they realize that either one of them might be the biological father of her adorable four-year-old daughter. The two begrudgingly agree to share fatherly duties until the results of a paternity test come back, forcing the two to finally spend some time with each other.
