In addition to real father and son John Bennett Perry and Matthew Perry playing father and son, "Old Murray" is played by Tony Perry, their brother and uncle respectively.
Matthew Perry's character makes a joke about the TV-series "Friends", in which he played a leading role.
When Murray (Matthew Perry) is chasing J.D. with his model airplane, it is reminiscent of a scene from North by Northwest (1959)
Matthew Perry's only directing credit.
