Feb. 8 (UPI) -- Ant-Man, Only Murders in the Building and Ghostbusters actor Paul Rudd has signed on to narrate the James Cameron-produced docu-series, Secrets of the Octopus, for National Geographic.

The three-part program is slated to premiere on April 21, Earth Day. It will also be available on Hulu and Disney+ the following day.

"It's been an incredible journey learning about these mysterious creatures and their interconnected lives. I can't imagine audiences won't be as blown away with the secret lives of octopuses as I was working on this series," Rudd said in a press release on Wednesday.

"If you're going to dive deep into natural history, you have to do it with National Geographic. I'm thrilled to be working with James Cameron and the Nat Geo team to deepen our connection with the ocean and all of its creatures and curiosities."
