Can you just hear him screaming? I recently learned that the scream was only supposed to be in the movie once, but Macaulay had two such really great takes that the director decided to get it in there twice.
Home Alone (1990) is a classic and I'm sure I'll be popping it into...whatever it is we'll be popping movies into in the future...for many, many decades to come.
It was funny to go from watching it before being a parent, when I didn't really think about the panic the mother must've felt, to having babies, when I thought "What kind of a mother would forget her kid at home?", to the kids getting older and life getting crazy busy and me thinking, "Oh yeah, I can totally see me doing that."
Actually, it sorta happened at my son's 8th grade graduation two years ago. I, my husband, and my parents hopped out of the car happily chatting and walking toward the school when we heard a muffled shout coming from the back of my parents' SUV...we forgot to open the hatch to let my daughter out...whoops.
