I saw this movie recently but I don’t know the name. It starts with an older couple interviewing a boy to work for them. They give him their house and money while they’re gone. They have experimented with a banana in a box, I think for a week, but it’s fresh; then they each get into a box and tell the boy to open them in a week. They are aware of no time passing, to them he just closed the lids. Finally, they go into a tomb that hides their time machine. The boy follows them in later and (of course) gets into trouble.
