Robbie Williams' new semi-autobiographical film Better Man is set to be released later this week.

The musical film is based on the true story of the meteoric rise, fall and return of the Take That star.

However, the 50-year-old recently revealed amendments were made to the script after former bandmate Gary Barlow felt he "came off worse than Darth Vader in Star Wars".

Appearing on the New Year's Eve episode of The Graham Norton Show, he said: "I sent the first script to Gary Barlow and he phoned me up - we have a great relationship now - and said 'Rob, I come off worse than Darth Vader in Star Wars', so we made amendments.

"When you talk about my past it happens to be contentious, and I was a different person then.

"The film brings all that up again so it's super odd and I can understand how it could be hard for Gary.

"As for the other people I throw under the bus I don't care."

It follows on from Robbie's self-titled Netflix documentary which aired last year.

Over the years, there have been many rumours about what happened between Robbie and the other Take That members including Gary, Howard Donald, Mark Owen and Jason Orange.

Robbie left the band in 1995 and went on to have a successful solo career - but did he ever fall out with frontman Gary?

The musical pair reportedly fell out when Robbie "ditched" Take That rehearsals to party in Glastonbury although they are now pals again, reports the Express.

After Robbie went his own way, he later explained: "The last few months I was a wreck. The night before we all went out. I drank myself stupid.

"That morning, we rehearsed as normal, but I was drinking an awful lot. So when they spoke to me about my attitude I thought they were saying 'you should leave'.

"I walked out, left it a couple of seconds and then I jumped in through the door and everybody laughed. And then I walked away. They never thought that would be the last time."

Meanwhile, in the past, Gary spoke on food critic Jay Rayner's Out to Lunch podcast to discuss the issues he had with his former bandmate.

Gary said: "Rob was wanting to get to the front. He had a great voice, very natural given talent he had."

The 52-year-old went on to say: "My beef with Rob, and we still talk about this, is that I'll spend six weeks rehearsing a five-minute piece to perfect it, every move and note I'll know what I'm doing. I'll go out and I'll get a great response.

"Robbie gets given a song four minutes before he goes out. He learns it and goes out and gets a better response. That's what annoys me about him."

Gary added: "He's just got a gift. He always calls it the Freddie Star syndrome.

"He loves going out and doing five minutes, the audience goes crazy and he walks off and he's gone. I prefer a two-hour thing where I can warm people up, that's got highs and lows."

Better Man will be released in UK cinemas on Boxing Day (December 26).
