You can enjoy this years Gerry Anderson Day with both Big Finish and Britbox — we tell you how

is the first ever InternationalGerry Anderson Day (as announced by The Official Gerry Anderson) and the godfather of supermarionation can be commemorated on audio or on screen.

Big Finish holds a Terrahawks Tweetalong listening party for Gerry Anderson Day

On Wednesday 14 April at precisely 8pm (UK time), this exclusive Big Finish listening party will get underway, with a free livestream of three episodes of Terrahawks – volume one episodes, Clubbed to Death and Into the Breach and volume two episode, Sale of the Galaxy, which stars long-term Gerry Anderson collaborator, the late Nicholas Parsons. For the duration of the listening party, these audio adventures will be available to stream for free on SoundCloud in their entirety, so that Terrahawks fans worldwide can join in and listen together simultaneously. (Of course, people who have previously bought the stories may prefer to listen to their own personal CD or download copy. That’s fine!)

Meanwhile, on Twitter, actors and writers from the series will be tweeting along, chipping in facts and memories of the stories using the hashtag #Terrahawks.
