Latest News About Regular Show Lost Tapes Where To Watch

Direct answer: The latest update is that Regular Show: The Lost Tapes is premiering in 2026, with new episodes available on Cartoon Network and HBO Max in the U.S., and international availability varying by region.

Details and watch options:

• Premiere and availability: Cartoon Network announced the new Lost Tapes series, with a May 11, 2026 release in some regions, and subsequent streaming on HBO Max (Warner Bros. Discovery's platform) in many markets. This suggests U.S. viewers can watch on Cartoon Network as new episodes air and later on HBO Max, though some regions may differ in timing.[4][5][6]
• Where to watch in the U.S.: Original broadcasts on Cartoon Network, with HBO Max as a streaming option once episodes are available there. Plex listings also indicate availability on HBO Max for streaming, though regional variations apply.[5][8][9]
• International notes: In some regions, HBO Max or equivalent services (e.g., Netflix, Prime Video) may carry the series, or it may be available via local streaming partners. A number of outlets list HBO Max and related channels as primary options outside the U.S..[2][8][5]
• First clips and media: The series has released promotional clips and coverage from outlets like ComicBook.com, which confirms the continuing presence of Mordecai and Rigby and early promotional material. You may find trailers and clips on official Cartoon Network channels and major entertainment sites.[6]

Illustrative example:

• If you’re in New York City and want the quickest path, check Cartoon Network during its block for new episodes, then look for HBO Max availability a day or so after they air, as regional windows may apply.

What to watch for next:

• Release windows by region: Expect staggered availability across regions—U.S. broadcasts on Cartoon Network with HBO Max streaming soon after, while other regions may see HBO Max, Netflix, or local services pick up the show on a different timeline.[8][5]
• First-look clips: Entertainment outlets began releasing clips and previews around the launch window, which can give you a sense of the tone and setup for Mordecai and Rigby in this new chapter.[6]
