Tango One was released in the UK on DVD last Monday, and is now available to buy via Amazon, iTunes and other DVD outlets. The photo shared above is of the Tango One cast and crew screening, celebrating the DVD release. 

There only seems to be one review for Tango One so far, which is a bit mixed, though has kind words to say about Joseph Millson's performance. 

On the plus side, Regan and Millson lend some gravitas to their respective roles. Donovan and Hathaway are intended to be deadly opponents but this isn’t properly established and may have made a stronger centre for the drama.
