Paul Walker Body Doubles and CGI is Planned to be Used to Finish "Fast and Furious 7"

Despite the announcement that Paul Walker's character would be retired after he died last November in a tragic car accident, sources say that body doubles are standing by for Universal to be used along with CGI to complete the film without removing the character from the film. This could mean big trouble from his fans as well as the production quality of the film itself (ie. Jeff Bridge's character in "Tron: Legacy")
