EXCLUSIVE

"Arrested Development" star Justin Wade -- who plays Steve Holt on the show (STEVE HOLT!!!) -- couldn't be more excited for the big premiere on Netflix this weekend ... telling TMZ, he's planning to throw a massive rager to commemorate the big day.

Wade tells us, the festivities will kick off Sunday afternoon at his L.A. apartment -- and he's already invited more than 25 friends to come over and get crazy.

The episodes are going live at midnight on Saturday (12:01am PST Sunday) -- after AD's 7-year hiatus -- but Wade says he and his friends plan to warm things up by re-watching some old favorites ... i.e. the episodes Wade stars in.

Oh yeah, Wade says he's also invited former AD castmate Justin Lee, who played Annyong.

Sounds like fun. Thanks Steve Holt!
