“Life of Pi” has lived many lives.

It was initially a best-selling 2001 novel by Yann Martel.

In 2012, it was adapted into a big-screen epic by director Ang Lee.

And earlier this year, a stage version that began in England debuted on Broadway.

A trio of people who worked on different variations of “Life of Pi” will talk about their experiences during “Life is a Story — The Journey of ‘Life of Pi’ from story to screen to stage” Friday at United Theatre in Westerly.

They are: Alexis Rockman, who was inspirational artist for the film adaptation; Steve Callahan, the marine and survival consultant on the movie; and Ashley Brooke Monroe, who is resident director for “Life of Pi” on Broadway.

Callahan actually survived for 76 days in a life raft in the Atlantic, which is why Lee asked him to be a consultant for the film in which, yes, a character survives for a long period on a life raft.

And note that Rockman’s art is also featured in the “Oceanus” exhibition opening Saturday at the Mystic Seaport Museum. The show boasts large-scale paintings commissioned by the museum to become part of its permanent collection.

“Life is a Story — The Journey of ‘Life of Pi’ from story to screen to stage,” 7:30 p.m. Friday, United Theatre, 5 Canal St., Westerly; $20; includes pre-talk reception 7:30-8:30 p.m.; www.unitedtheatre.org.
