As well as Harry Potter's Spall and Goldfinger's Blackman, Rubins also has a geek-friendly cast that includes a one-time Lara Croft (Rhona Mitra), a star of The Inbetweeners (Blake Harrison) and a Battlestar Galactica veteran (James Callis).
Reuniting the Rubins will open in selected UK cinemas on October 21.
