The Beatles' Yellow Submarine LP and movie will mark its 50th anniversary milestone next summer, and plans are already afoot to celebrate with a new comic adaptation and a line of collectibles.

Word regarding the book comes courtesy of The Hollywood Reporter, which notes that the project is scheduled for release next year via Titan Comics. It's being spearheaded by newly appointed Mad magazine editor Bill Morrison, a longtime fan who's finally being given the opportunity to complete a project he was originally commissioned for nearly 20 years ago.

As Morrison has previously written, he was hired to put together a Yellow Submarine adaptation in 1999 — and completed 25 pages of the book before "Apple decided that comic books were too lowbrow for their Yellow Submarine marketing plan and backed out of the deal." That opinion has evidently changed, and the book's new publisher couldn't be happier.

"We’re thrilled to be publishing The Beatles: Yellow Submarine for the 50th anniversary of this fantastic movie," Titan publishing director Chris Teather told THR. "We can’t wait for Beatles fans to experience this official adaptation."

Titan has also already issued a line of vinyl figures to commemorate the anniversary, including two versions of the band — one in color, one in black and white — and characters from the film such as the Blue Meanies, Apple Bonkers and the Four-Headed Bulldog. Fans can look for the figures in stores now, and keep an eye out for updates regarding the Yellow Submarine comic "in coming months."
