Trivia: On the promotional movie poster, a frazzled Steve Martin is shown holding 2 children upside down by their ankles. On the set, sometimes the children would get unruly, so as a joke, Steve Martin once grabbed 2 of the unruly children and actually held them upside down by their ankles. Director Ron Howard saw this and decided it would make a funny promotional picture, so that's where he got the idea for it.
New this month Question: Since Helen is one of the 4 adult Buckman children and had been previously married to Julie and Garry's dad, why is Julie's last name also Buckman? I could see Helen going back to her maiden name, that's not uncommon but it would be unusual to have a teenager (in the late 80's) who had her mother's name rather than her father's. Or was this a plot hole that was created so that they could create the conflict of the photographs scene?
