Arrested Development creator Mitchell Hurwitz announced last fall that Cross, Jason Bateman, Will Arnett and their co-stars will appear in a series of new television episodes and a feature film to wrap up the Bluth family's saga.
Netflix later announced that it will exclusively stream the new episodes to its subscribers on the web.
Discussing the Arrested Development reunion with The Boston Herald, Cross said he had no idea about the Netflix deal until recently.
"I am not being coy when I'm saying I know exactly as much as you guys do," he joked. "And, in fact, I got my information about the Netflix thing the same way everybody else did, which was the internet."
Cross went on to say he's very excited to play Dr Tobias Funke once again, but admitted he is skeptical whether the project will actually get off the ground.
He commented: "He's one of my top three characters I've ever played. I really enjoyed doing it. But as I've said before, I'll believe it when I'm on set and they go, 'And action'."
Cross previously claimed that the stars of Arrested Development are excited to be reuniting.
Arrested Development won six Emmys and a Golden Globe during its three-season run on Fox.
