Morph revival will include a revamped female character “with brains” to help balance out the “male heavy” programme, creators have revealed.

Aardman today has revealed the first photograph of the new Morph series set to hit screens in spring, with some surprise costars.

For the first time in 40 years, Morph will be joined not just by his sidekick Chas but with old friends Grandmorph and Delilah - who has had a makeover.

The previous “mumsy” character has been upgraded for an electric-scooter riding, tech-savvy, know-it-all, saying goodbye to her old female typecasting.

Merlin Crossingham, Director of Morph said: “Delilah has changed in that she used to be mumsy and she had a bit of an old fashioned hairstyle, so we've given her more of a funky hairstyle.

“She's going to be the intelligent tech-savvy, more up-to-date of the gang.

“If something goes wrong, the boys will normally turn to her to help fix it.”

Of the thinking behind her new traits, Crossingham said: “Morph and Chas obviously are both boys and then we needed to bring Delilah into it otherwise it was going to be quite male-heavy.

He added that the decision “felt natural” especially as Morph and Chas are “idiots” who run around “being goofy”.
