Russell Crowe and Zac Efron are in Thailand for the production of the movie “The Greatest Beer Run Ever.” The film is directed by Peter Farrelly whose 2018 film “Green Book” won three Oscars in 2019, including best picture.

Filming has recently included scenes at the Hua Hin Airport with local extras recruited, posing as US Airforce servicemen.  One of the extras explained that he had joined around 150 others at the airport where multiple tour buses and other vehicles have been spotted but with tight security in place. 

He said that two US Military styled aircraft and five jeeps with about 100 crew involved. Russell Crowe was not amongst the those present, although Zac Efron made an appearance.

The film is an adaptation of the book “The Greatest Beer Run Ever: A True Story of Friendship Stronger Than War,” written by Joanna Molloy and John “Chickie” Donohue. It is based on the true story of Donohue, who left New York in 1967 to track down and share a few beers with his childhood buddies in the army while they were fighting in Vietnam.  The production is using Thailand as a stand-in for Vietnam.

Crowe and Efron have been visible on social media since arriving in Thailand, though both have been coy about naming the project. However, a production company spokesman has confirmed “we are in production on ‘The Greatest Beer Run Ever’ in Thailand with Pete Farrelly at the helm.”

On Twitter, Crowe said: “Currently I’m working in Thailand, shooting a movie. Getting on that first plane after 2 years was a very strange feeling, strange but kind of wonderful.”  Crowe entered the country via the Phuket Sandbox scheme, then posted pictures of himself bicycling around the sights of Bangkok.

Thailand’s government was initially delighted by the star’s warm comments and touristy images, but not when Crowe posted a photo of the chaotic tangle of overhead cables that festoon many city streets.

Efron, who has also been largely Australia-based for the past two years, used Instagram to post a shirtless image of himself on a Thai beach celebrating his 34th birthday.  “I am so lucky to be able to be on this amazingly fun ride with you all. This one feels very special as I get to spend it in Thailand, alongside the most talented and kind cast and crew, making a movie that I think will be awesome… couldn’t be a happier moment in my life. Love you all so much,” he wrote.

Thailand, which has studio facilities, skilled crews and a production rebate system, is a regular destination for international productions, including around Hua Hin.
