The actor joined wife Tamzin Outhwaite at the official opening of the new Disney Store on London's Oxford Street last night, where he told Digital Spy that the reaction to the BBC Three show has been "amazing".
Ellis said: "Everything is very good. We had an amazing response to The Fades, which was great. We just have to wait to find out if we're going to do another series now."
His co-star Iain de Caestecker previously said that the cast would "really love" for the programme to be given another run.
Meanwhile, Ellis will also return for the third series of hit BBC comedy Miranda, in which he plays Miranda Hart's love interest Gary.
The father-of-two told DS: "We're doing another series in August."
