Question: Just two things I was curious about whilst watching. Does anyone know how they trained the boy who plays Little Jack to do the hand signals and cry on cue etc.? I imagine it would be quite difficult to teach a toddler all of that. Also, how did they get a boy who looks so much like Ben Stiller for the part of Jorge? Is he related in any way or is it just luck that they found a boy like that?
Question: When Greg, Pam and their parents are in the garden drinking, one of them gets onto the fact that Greg is an only child. Jack says to Greg 'You said you had a sister.
