Sun, sea, sand and... the chance to win £100, 000 was the challenge a PE teacher at a Grimethorpe High School faced when he spent four months ''shipwrecked' on an island in the middle of the Pacific.

Marvyn Williams, 27, won a place on the hit show Shipwrecked last summer and can be seen in the current series on Channel Four.

Marvyn, originally from Chorley, taught PE at the school for four years but gave up to take part in the show which is filmed on the Cook Islands.

Marvyn said: "I was always interested in working in television. I wanted to be a presenter. The show was just something I wanted to do and was an opportunity to step away from teaching and into something different."

At the start of the show everyone lives together on one island but are then split into two 'tribes', the Tigers and the Sharks, and one tribe goes to another island.

Marvyn said having been a Tiger was one of the highlights of the experience. He said: "I was an original Tiger, being one of the first people on the island. I always wanted to be a Tiger, and I stayed a Tiger."
