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.
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?
Question: Is the timeline in this movie supposed to be somewhat non-linear? For example - in the scene where Karen and Gill go to Kevin's school to talk to the principal and psychologist, it is specifically mentioned that the new school year is 4 months away meaning it is approximately April since kids typically began school in August. Later, when Larry comes to visit and is talking to the dad in the garage, he mentions the Super Bowl (which you reasonably would have assumed they just watched) but that takes place in January. Plus, Larry's mom tells them that Cool (Larry's son) has just finished eating lunch. How? If they just watched the Super Bowl, it would be dinner since the game is always played in the afternoon. And despite being in "St. Louis" (we know they actually filmed in Florida), it never seems to be winter. The end is really the most confusing with the birthing order. We learned earlier in a scene that Karen is pregnant and is due in February. At some point around this time, we find out that Julie is also pregnant. At this point, Julie's mom Helen has just gone on her first date with Mr. Bowen (Garry's biology teacher) but the end, Helen is having a baby, Julie and Tod's baby barely looks a month old and Karen's baby looks to be about 4 months old. Did Helen marry Mr. Bowen immediately and get pregnant right away?
