With Six You Get Eggroll (1968)

A widow (Doris Day) with three sons (John Findlater, Richard Steele, Jimmy Bracken) and a widower (Brian Keith) with a daughter (Barbara Hershey) fall in love. But their children have a hard time adjusting to the idea of combining households much less adjusting to a new "parent". Directed by Howard Morris, this was Day's final feature film before going into television. Perhaps not so ironically, the G rated movie plays out like an extended TV sitcom. It came out the same year as a similar film about combined families, YOURS MINE AND OURS but this one is actually better. While not on the level of her chemistry with Rock Hudson or James Garner, Day and Keith work very well off each other. But the dynamics of tension between a combined household gives way to utter nonsense in the film's last 15 minutes what with stoned hippies, car crashes and Keith falling out of a moving camper in his boxer shorts and a teddy bear. And whoever thought Doris Day and George Carlin would end up in a movie together? With Pat Carroll, Alice Ghostley, Elaine Devry and Vic Tayback.
