Warner Bros. seems pretty serious about being in the Dwayne Johnson business.

The rumors continue to circulate that he’s getting involved in the world of DC with “Shazam,” but he’s already attached to a WB franchise.

A couple of years ago, he assumed the lead role in “Journey 2: The Mysterious Island.”

Now the studio’s interested in making another Journey, but they’re going to have to adjust course: it looks like it’s going to be two more Journeys.

The Hollywood Reporter has announced that Chad and Cary Hayes have been hired to write the third and fourth installments in the Journey series. The Hayes siblings recently earned their reputation from penning “The Conjuring.”

Surely Johnson noticed, as he is starring in their most recent script, “San Andreas 3D.” The hiring of the Hayes siblings suggests an effort to appeal to Johnson more directly, particularly considering two more movies is a major commitment for the busy superstar.

It also means goodbye to another writing team, Brian and Mark Gunn, who wrote the second film and were previously enlisted to pen part three. What is up with this franchise and brothers?

“Journey 2: The Mysterious Island” was a surprise hit in 2012, grossing $335 million worldwide.

That was higher than the $241 million brought in by the Johnson-less “Journey To The Center Of The Earth,” which starred Brendan Fraser.

Fraser was playing the uncle to Josh Hutcherson’s character, while Johnson was the new stepfather – given that Hutcherson will be back for his third go-round, maybe Fraser, who has been out of the spotlight, can return? Surely that would excite someone, right?

These movies are pretty popular, but people aren’t exactly running around quoting lines of dialogue from the “saga.” It’s believed that Brad Peyton would return from directing the second one, particularly considering Peyton is also currently directing “San Andreas 3D.”
