Russell Crowe's six-year-old son makes his big screen debut opposite his famous father in Les Miserables.

The Gladiator star allowed Tennyson, six, to appear in the blockbuster adaptation of the acclaimed stage show, which has won eight Academy Awards nominations.

Crowe admits the youngster is too young to watch the whole film, but he let Tennyson see himself onscreen.

In a post on his page, Crowe writes, "I just showed Tenny the 8 shots he is part of during 'When Tomorrow Comes' in Les Mis, at 6, too young to watch it all, but he was chuffed (delighted)."
