Behind the scenesEdit
In the film, the character's name, as it appeared on a certificate, was Tyler O'Neil. It's been speculated that "Tyler" may be his actual given name and that "Charlie" is only a nickname. Tyler could also be his middle name which was placed on the certificate accidentally. In Bill McCay's Stargate novels, the character was named Jack O'Neil, Jr. after his father.
