New Zealander Julian Bristow was sick of seeing rubbish rugby scenes in Hollywood films.

So when the 36-year-old union player heard of a new rugby flick on the cards to be directed by Clint Eastwood, he put in a call to the Hollywood heavyweight's production studios to "offer my rugby services".

"I said, 'look, you don't want to do a movie with pretty ordinary rugby scenes ... so if I can help in any way, shape or form I'd be happy to'," Mr Bristow told AAP from his home in San Pedro, California.

Almost a year later, Mr Bristow, who'd just been made redundant from his factory job in the US, got a call from one of the producers of Invictus, a blockbuster based on the Springboks' 1995 Rugby World Cup win.

Filming had wrapped in South Africa and the Kiwi, originally from Hastings in the North Island, was asked into the studio to check out hours of raw footage.

"It was pretty awesome but it needed a few finishing touches done to it and that's when they (the producers) said, 'Hey, can you come on board and help us finish it off," said Mr Bristow, a fullback for the Los Angeles Rugby Club.

"(I was) just removing some of the inaccurate scenes, scenes that might not have actually happened on the rugby field."

Like one in which a touch judge looked straight down the barrel of the camera, smiled and gave a thumbs up, before raising the flags to indicate a goal.

"It look really cheesy and really wrong.

"(It's) just something that could have been embarrassing to rugby players around the world cause it's inaccurate."

While Mr Bristow has plans to move back to New Zealand with his Australian wife, the Kiwi is enjoying the "pretty cool adventure" in the US, plus he has a new Hollywood friend.

"It was sort of surreal talking to (Clint Eastwood), cause you look at him and think he's one of the most famous actors and directors in the world and here we are just having a chat about rugby.

"It was like weird, like a dream."
