Roddy McDowall/Peter Lawford

I was thinking that it was predictable that the adult version of Roddy McDowall's character from Lassie Come Home is played by Peter Lawford.

It seemed like something that must have happened over and over in films.

But, as far as I can see, it was just these two films and The White Cliffs of Dover in which they played the same character, boy and man, unless I'm missing something.
