With his quiet confidence, seven-year-old Caleb knew he got the role just after he auditioned for the part of six-year-old Trump.

"I postulated that I was going to get it, and I did," said the easy-going elementary school student.

As well as attending Kilbride Public School, Caleb also takes courses at the Church of Scientology in Toronto.

Author Tracy Lynn Repchuk said these courses help her son in every day life and aid in resolving conflict amongst a highly creative family. Caleb's father, David, is an artist and president of the Fine Arts Society of Milton. His two sisters are interested in becoming actresses and were the ones who encouraged Caleb to go into acting.

"His sisters, Kennedy and Celeste, wanted to be actresses so I took them to a talent agency," said Tracy. "Caleb was along for the ride but the agency said he had the right look and wanted him too."

Caleb is now represented by Burlington-based AMP Talent. Instead of conflict running rampant in the household, Tracy said the family's newfound belief in the Church of Scientology helps to alleviate tension.

"The first thing you learn in Scientology is the Reactive Mind," she explained. "There are very few blow-ups in our house because as soon as you head in that direction, you know you have stepped out of your analytical mind. We know to pull it in and talk at a proper level. So there are no egos clashing because we try to stay away from egos."

In addition to this film, Caleb has also appeared in two commercials.

"His sisters are good with it considering they started the whole thing," Tracy continued. "The success of one family member leads to the success of us all."

As well, Caleb has had training with the likes of Mille Tom (Degrassi, Men with Brooms), Brian Levy (Powerhouse Casting), Anne Tait (Anne of Green Gables, Avonlea and Goosebumps) and Jann Stefoff (The Santa Clause, Three Men and a Baby).

To get into Trump's character, Caleb read over the entire script to get the feel of the movie and to capture elements of Trump's life.

"Caleb looked at pictures to get a feel of (Trump's) evolution as a human being, and he studied his bio to see where he came from and where he is now," said Tracy.

Filming for the movie, called Ambition, began March 22 in Toronto and will continue for 22 days.

The biography should air later this year on ABC.

"I've never met Donald Trump," said Caleb, "but I like him because he is one of the richest men in the world and he looks very kind."
