Supergirl fans left nervous after CBS failed to renew the show last week shouldn't panic just yet.

The DC Comics series was not among the 11 shows that the network recommissioned on March 25 - but actor David Harewood has told Digital Spy that things are looking "very positive".

"I've heard lots of rumblings - there are no guarantees," said the actor, who plays J'onn J'onzz, alias the Martian Manhunter.

"But CBS has made some very positive noises. All I know is that we've just had one of our biggest audiences of the year so far with the Flash crossover so it's all looking positive.

"The fans have been very vociferous and very vocal, so hopefully it's enough to get us a second season."

Harewood's character was originally introduced as government agent Hank Henshaw - with the show's seventh episode revealing that he was in fact DC's green-skinned superhero.

"It's a lot of fun..." the Night Manager actor said of playing the heroic alien, "although network television is a particular beast. It's been a lot harder work than I thought it would be - but immensely fun."

Supergirl airs on Mondays at 8/7c on CBS. In the UK, the series continues on Fridays at 8pm on Sky1.

David Harewood stars in The Night Manager - out now on Blu-ray & DVD .
