This is the only clip, from the Saga of a Fugitive Fleet behind the scenes video, where a longer scene was filmed.
Saga of a Fugitive Fleet Part 1: Space Mutiny stars Ken Bones (Kalgan) and John Guilor (MacPhearson), who both appeared in the finale of the 50th anniversary episode of Dr Who (The Day of the Doctor) but who only met for the first time for these recording sessions.
