Chris Pine is set to play iconic CBS anchor Walter Cronkite in the JFK assassination film Newsflash.

The actor is now attached to portray Cronkite, who historically reported on the network that President John F Kennedy had been killed on 22 November, 1963, according to Deadline.

Mark Ruffalo, meanwhile, is reportedly lined up to play CBS producer Don Hewitt, who worked with Cronkite on the broadcast and is remembered as the creator of 60 Minutes.

Seth Rogen had initially been in the running to play Cronkite, but the team behind the film now appears to have taken another direction.

David Gordon Green was originally set to direct the film, but dropped out of the project to focus on the two Halloween sequels expected in 2020 and 2021.

In addition to Cronkite and Hewitt, the movie is expected to portray reporter Dan Rather, who was in his early thirties when he found himself close to the scene of the president’s assassination in Dallas, Texas.

Pine was seen in Wonder Woman in 2017 and A Wrinkle in Time in 2018.

He had a voicing part in Spider-Man: Into the Spider-Verse that same year.

The actor is scheduled to return as Steve Trevor in Wonder Woman 1984, due to be released in 2020.
