I freely admit that I would have probably never even heard of Cabin Pressure if Benedict Cumberbatch wasn't in it. The only other radio drama that I've listened to is a version of Phantom of the Opera by Big Finish Productions (which is excellent BTW). Now that I've actually heard Cabin Pressure from series one to three I completely recommend it. It's brilliant! It's an absolutely hilarious sitcom and is genuinely laugh-out-loud funny. And by laugh out loud funny I don't mean little giggles and sniggers funny. Oh no! I have actually howled with laughter at some episodes! The show is THAT good and it's seriously one of the best sitcoms I've ever heard! The episodes are brilliantly-written by John Finnemore and his writing is hilarious in a very witty, sharp, dry way. Cabin Pressure is a clever sitcom and the episodes are well-plotted and stand up to repeat listenings. I love the adventure feel of Cabin Pressure as well. The characters actually get to travel around the world!
The main characters are extremely likeable and funny and they have quite a lot of depth. For all their clashes and disagreements it's obvious that they like each other deep down. They really do seem like an (admittedly weird) family and the show can be pretty heartwarming. In addition to the main actors there's also been some very impressive guest stars in the show: Helen Baxendale, John Sessions, Mark Williams, Alison Steadman, Ben Willbond, Phil Davis and Anthony Stewart Head.
It's difficult for me to narrow down what my absolute favourite Cabin Pressure episode is. I love all of the episodes but Ottery St Mary, Qikiqtarjuaq, Paris, Cremona, Ipswich, Helsinki, Newcastle and St Petersburg especially. Sherlock fans should love Paris in particular! This is a detective episode in which Martin goes all Miss Marple on us! This episode is really a hilarious homage to Sherlock of course. Apparently this episode took ages to record because the audience were in hysterics and could not stop laughing, and Cumberbatch kept throwing them some Sherlock Holmes facial expressions.
I bought a disc set of Cabin Pressure on Amazon, which included series one to three of the show plus the Christmas special episode Molokai. It only cost me about £10 which is a bargain. I've ordered series four of the show and I'm waiting for that to arrive. Again, I completely recommend Cabin Pressure. It's hilarious, clever, great fun, heartwarming, and brilliantly written and acted. The episodes are recorded in front of a live audience so all the laughter that you hear is genuine. Even if you've never really listened to radio drama before then give it a try!
