Better Call Saul fans are in for a real treat, as comedy movie The Making of Jesus Diabetes will reunite three of its actors.

According to Deadline, Saul Goodman actor Bob Odenkirk has landed the part of Leo – a shifty man with a dark past – while Andrew Friedman (Mr Neff in season 4 of Saul) and Michael Naughton (Henry in the same season) are starring as reclusive brothers Seymour and Gerry Whitaker.

The trio also co-wrote the script together, with It's Always Sunny in Philadelphia's Heath Cullens coming on board as director.

As for the storyline, The Making of Jesus Diabetes follows Seymour and Gerry, who attempt to produce a movie about diabetes during the era of Jesus, despite having zero filmmaking experience.

If that wasn't madcap enough, their neighbour is filming them at the same time.

Ellen S Wander of Film Bridge International said in a statement: "It's an incredible opportunity for us to work with these talented filmmakers and cast. We're thrilled to bring their smart, funny feature to audiences around the world."

Odenkirk Provissiero Entertainment's Michael Day and Andrew DeCesare also shared a few words ahead of filming next year.

"Jesus Diabetes is a refreshingly funny script from start to finish. With this cast and this script, it's a recipe for laugh-out-loud entertainment," teased the former.

DeCesare added: "This type of project is the reason audience members still love going to the movies, The Making of Jesus Diabetes stands on its own as funny, new and exactly what the world needs right now."
