An incredibly detailed fan theory explains how Vin Diesel’s love of sleeveless shirts has an impact on the overall quality of his movies.

Vin Diesel‘s sleeveless shirts have an impact on the success of his movies, according to an incredibly detailed fan theory. Diesel is one of the world’s highest-grossing actors due to his unwavering commitment to family as Dominic Toretto in the Fast & Furious franchise, and for providing the voice of Groot in the Marvel Cinematic Universe. In addition to Fast & Furious, Diesel has cultivated a career as an action star by headlining the XXX and The Chronicles of Riddick franchises. Both on and off-screen, Diesel is known for his love of sleeveless shirts.

A recent fan theory suggests there is actually a correlation between Diesel’s sleeveless shirts and whether his movies are successful. Shared on Reddit by LundgrensFrontKick, the user systematically scoured every minute of Diesel’s movies to collect data about his sleeveless shirt screen time. Demonstrated with a series of charts and graphs, the theory concludes that by wearing three to four sleeveless shirts and limiting the screen time dedicated to them, Diesel’s movies make more money at the box office and have higher Rotten Tomatoes scores on average.

Will Fast X Be A Success Based On Diesel’s Sleeveless Shirts?

Though the entertaining fan theory is obviously an example of correlation and not causation, it can be used to determine whether the tenth Fast & Furious movie will be a success based on Diesel’s shirt choices. The Fast X trailer shows Dom wearing a total of three different sleeveless shirts, which is right in the sweet spot for the film to be a critical and commercial success. Furthermore, one of the shirts is black and the other is a gray button-up which, according to the fan theory, means that Fast X will have a fresh Rotten Tomatoes score and gross at least $808 million at the worldwide box office.

Interestingly enough, the fan theory explains that when Vin Diesel wears more than four sleeveless shirts or wears them for more than 15 percent of the film’s runtime, the box office returns and Rotten Tomatoes scores begin to diminish, exemplified by the Riddick trilogy. The Fast X trailer is right in the sweet spot, though the final cut might exceed it and risk sleeveless shirt over-saturation. Only time will tell when Fast X races into theaters on May 19.
