Love finding out this kinda thing.
Nothing to offer I'm afraid.
"Ollie in So Awkward is played by Archie Lyndhurst, son of Nicholas Lyndhurst." My dd past the stage of watching that kinda thing, but googled and wow! He does look like his dad doesn't he?
"Eric Roberts and Julia Roberts" and of course Eric's daughter Emma Roberts (scream 4, we're the millers) which iirc there was a time Eric tried to get custody of Emma when he was still an active addict and Julia supported Emma's mum and this lead to Eric and Julia becoming estranged, though I think they've now made up
Amusedbush - that one Oliver and Kate Hudson - surprised me when I found out.
Sherilyn Fenn niece, Suzi Quatro aunty. - wow! Didn't know that one!
"Mariska Hargitay is Jayne Mansfield daughter" my mum was really surprise to learn that one. Worse poor mariska was in the car in the accident her mum died in. She still bears a scar as a result of the accident.
"Blythe Danner (Meet the Parents as Ben Stillers hippy mum) is Gwyneth Paltrows Mum" actually she plays his mother in law, Robert de niro's wife. His mother is played by the wonderful la Streisand!
