Slightly older children might wish to take part in the Kevin Bacon Game. The theory is that every living actor in Hollywood can be linked to Kevin Bacon in just five steps - plus some of the dead ones, too.

An example - Vivien Leigh.

1.Vivien Leigh.

2.Marlon Brando starred with Leigh in A Streetcar Named Desire.

3.Al Pacino starred with Brando in The Godfather.

4.Robert de Niro starred with Pacino in The Godfather Part II.

5.Kevin Bacon starred with de Niro in Sleepers.

Of course, this does require that you have something of an encyclopedic knowledge of films.
