James Corden has said that "chubby or fat" actors are excluded from romantic leading roles on TV and in films.
The Late Late Show host spoke to actor David Tennant on his podcast, David Tennant Does a Podcast With, where he said that larger actors are, at best, cast as the funny friend.
He said: "If you only watch television or films, if an alien came back and they had to take a reading on planet Earth by just watching films or TV, they would imagine that if you are chubby or fat or big, you never really fall in love, you never have sex.
"Certainly no-one really ever finds you attractive. You will be good friends with people who are attractive and often will be a great sense of comfort to them and perhaps chip in with the odd joke every now and again."
The 40-year-old TV star, who co-created the hit sitcom Gavin & Stacey, said that being excluded from those types of roles spurred him into writing.
"It felt like if the world of entertainment was a big banquet table, people are like, 'There isn't a seat for you here.'
"I was like 'if that's not going to happen then I'm going to try to make something happen for myself'."
