Magnus Nolan is Christopher Nolan and Emma Thomas's son, who portrayed the 20 month old version of James Cobb in the film Inception. It is his only film credit to date.

Magnus appeared in the opening beach scene, as well as the beach scene inside Cobb's memories and the hotel lobby.

The working title for The Dark Knight Rises was "Magnus Rex", following the tradition of Nolan naming his working titles after his children.
