Campbell back with science show
Dallas Campbell says he can't watch himself on the telly presenting some of his previous TV shows.
The Bang Goes The Theory presenter sometimes catches episodes of The Gadget Show, which he fronted for a year, on TV channel Dave.
"I find them quite hard to watch. I'm like, 'Oh God, calm down a bit'," the former Holby actor admitted.
Dallas's science magazine BBC One show Bang Goes The Theory, which he co-presents with Liz Bonnin, Jem Stansfield and Dr Yan Wong, is now back for a sixth series
"Basically, we tell the stories of science. Science is sometimes a word that can send people running for the hills," Dallas said.
"They often associate it with that thing they did at school, which is a shame, because ultimately science is what underpins the world around us - and you certainly don't need to be a scientist to be interested in that."
:: Bang Goes The Theory returns to BBC One on Monday, March 12.
