Film producers making a movie of Anthony Horowitz's book Stormbreaker have begun their search for the boy to play teen super spy Alex Rider.
Stormbreaker is the first of six books about the 14-year-old orphan recruited to work as a top spy and carry out dangerous missions around the world.
Over 200 boys have already written in to put themselves forward for the role.
Boys who want to be Alex have to be 12-14 years-old and should write to filmmakers enclosing a photo.
Producers Samuelson Productions say interested actors must also have signed permission from a parent or guardian to be considered for the part.
Just like James Bond, Alex uses loads of gadgets to battle baddies, including a missile-launching bicycle, bionic spot cream and explosive bubble gum.
Author Anthony Horowitz said he expects fierce competition for the role, which will begin filming later this year.
A spokesperson for Samuelson Productions told Newsround: "It could turn out to be a young actor who is known, or it could be a complete unknown."
If you want to be considered for the part you can send a recent photo, contact telephone number and stamped addressed envelope, along with signed permission from a parent or guardian to:
