Karla Crome (Hit and Miss) and Nathan McMullen (Shameless) have joined the E4 drama, ScreenTerrier claims.
Karla Crome, Reece Noi, Chloe Sevigny, Peter Wright and Jonas Armstrong arrive at a special screening of new Sky Atlantic TV series Hit And Miss at the Mayfair Hotel in London
The new series of Misfits will introduce three new regular characters following the departures of Lauren Socha (Kelly), Iwan Rheon (Simon) and Antonia Thomas (Alisha).
23-year-old Crome will play Jess, who is described as "smart and articulate" and willing to question social norms and etiquette. McMullen has been cast as Finn, said to be "funny", "enthusiastic" and "childlike".
The identity of the third new cast member - who will portray the "good-looking" but "standoffish" Alex - is yet to be revealed.
Misfits star Joseph Gilgun (Rudy) recently told Digital Spy that he is enjoying working with his new castmates.
"They really are lovely, lovely people," said Gilgun. "You can see they're a bit wide-eyed - I remember feeling like they feel. I know how it feels to be the newbie."
Misfits will return to E4 in late 2012.
