two actresses' mothers had difficulty telling their daughters apart when they were in full make-up. In her first major role, the 2001 Walt Disney Productions television film Princess of Thieves, Knightley played the daughter of Robin Hood. In preparation for the part, she trained for several weeks in archery, fencing, and riding. Concurrently, she appeared in The Hole, a thriller that received a direct-to-video release in the US.
