No, this isn't a trailer for the upcoming threequel to Vin Diesel's 2002 action hit. But it is a set pic from the first day of shooting, which apparently was not all that long ago as Diesel posted the aforementioned shot to his Facebook page on the weekend. I heard a sequel featuring Diesel was in the works, but had no idea filming was underway until this morning. That's pretty under the radar for what I'm sure is intended to be one of the bigger movies of next year.
