Cross has been publicly sceptical in the past on the possibility of the proposed Arrested Development mini-series and film ever actually being produced, even admitting in January that he knew very little about the project.
In an interview with Playboy this week, Cross commented on Arrested Development co-executive producer Dean Lorey's announcement that production will begin this year.
"Based on what was described to me, it seems to be a very smart, original, interesting idea. I have high hopes for it," Cross said.
The actor-comedian went on to say that he's now more optimistic about the Arrested Development reunion coming to fruition since being briefed by the creative team.
Cross said: "I'm definitely more confident than I was before, but that's not to say I'm 100% confident. I won't be 100% confident until it's made."
Cross starred as the zany Dr Tobias Fünke for three seasons on Arrested Development between 2003 and 2006.
He recently revealed that he is repulsed by the manipulative Tobias and would never want to hang out with him in real life.
