The production of the upcoming Fast and Furious 7 film has been reportedly slowing down production from unprecedented delays, instead of the usual obstacles resulting from the recent death of lead actor Paul Walker. The feature film is scheduled to air on the big screen April 10, 2015.

It has been reported that production problems have arisen due to Vin Diesel's temper tantrums on set. Rumor has it that there was a point in which Diesel remained inside his trailer for a whole shooting day, and refused to cooperate with crew.

It would seem reasonable that Diesel finds it difficult to work a film series that constantly reminds him of the death of his personal friend and co-actor Paul Walker. The two have starred in four preceding and successful films in the franchise, and it is no secret that the two have had a deep friendship, one which Diesel blatantly expresses over social media.

The rumors that Diesel has been the main cause of the film's delay was recently denied by Chairman Donna Langley in a statement to press, "This production is working through some challenges that are historically unprecedented. The crew and cast, led by Vin, have been nothing but terrific under these circumstances."

If Diesel is not the issue at hand, than the primary problem lies with the persistent editing necessary to shoot scenes involving the late Paul Walker. Brian O' Connor's character will still appear in the upcoming film, but it is noted that shooting his scenes takes double the time and effort.

The cost has also exceeded the film's budget according to some reports, but despite all the rumored production problems, the movie is still a go.
