He lived the first three years of his life in actress Veronica Lake's old apartment in New York (her name was still visible inside the mailbox).
The priest who christened Stewart when he was a baby was a survivor of the Japanese attack on Pearl Harbor in World War II. He sustained serious burns in the attack.
Successfully completed a two-year Performing Arts course and was awarded an N.C.V.A. (National Council for Vocational Awards) Diploma.
In the movie Yesterday's Children (2000), he had to carry the actress Jane Seymour on a stretcher for a whole day. Despite the uncomfortable old boots he was given to wear and the uneven ground he had to walk on, Stewart somehow managed to complete his part without injuring himself or Ms. Seymour. (Perhaps it was something to do with the fact that the director jokingly threatened to kill him if he dropped Jane Seymour!).
Stewart is distantly related to former American astronaut and Air Force Lieutenant General (retired) Thomas P. Stafford, one of only 24 men to have flown to the Moon.
