Panic! It’s the last ever installment of The Hitchhiker’s Guide To The Galaxy, with a brand new full-cast dramatisation of Mostly Harmless, the final book in Douglas Adams’s famous ‘trilogy in five parts’. While frequent flyer Arthur Dent searches the universe for his lost love, Ford Prefect discovers a disturbing blast from the past at The Hitchhiker’s Guide HQ. Meanwhile, on one of many versions of Earth, a blonder, more American Trillian gets tangled up with a party of lost aliens having an identity crisis. And just when Arthur thinks he has found his true vocation on the backwater planet of Lamuella, the original Trillian turns up with more than a little spanner in the works. A stolen ship, a dramatic stampede and a new and sinister Guide lead to a race to save the Earth…again. But this time, will they succeed? Simon Jones returns as Arthur, Geoffrey McGivern as Ford, Mark Wing-Davey as Zaphod Beeblebrox, Susan Sheridan as Trillian, Sandra Dickinson as Tricia McMillian, and Stephen Moore as Marvin. William Franklyn is the Book, alongside a host of famous guest stars. This extended edition features 30 minutes of material not heard on BBC Radio 4.
