The magician, real name Christopher Sarantakos, cancelled a string of Las Vegas shows in October (15) to be with his 21-month-old son Johnny, who has been diagnosed with acute lymphoblastic leukaemia.

Johnny will reportedly be in treatment for several years, and Angel will be recording footage to raise awareness of the condition.

The documentary will be called 1095, based on the number of days of chemotherapy Johnny will have to undergo, according to TMZ.com.

Angel is also organising a charity event to raise money for paediatric cancer research, which will reportedly be held at the Luxor Hotel and Casino in Las Vegas, where he has a show.

A marriage certificate uncovered by editors of the website in October (15) showed Angel married Johnny's mother Shaunyl Benson in February (15).
