Ararat's Karen and Dawn Brennan felt "lucky" to be cast as unpaid extras in the Ride Like a Girl motion picture.
Ride Like A Girl, starring Teresa Palmer and Sam Neill, is billed as the true story of Michelle Payne, the first woman jockey to win the Melbourne Cup.
Karen Brennan said the opportunity came about through her connection with a women's only horse racing syndicate that was with Michelle Payne after she won the 2015 Melbourne Cup.
"l received an invitation early last year to attend the filming of the movie Ride Like A Girl at Sunbury, in May," she said.
"We spent two days to shoot a wedding scene in the movie.
"I accepted and was also allowed to bring my mother along as well, we were unpaid extras."
The daughter and mother duo stayed with eight other ladies who were also extras for the movie.
"We made our way to the first day of filming to an access road adjacent to a former horse trainers property, where we were shuttle bussed onto the property," Ms Brennan said.
"We then signed all legal documents re filming and our responsibilities in regards to whilst on and off the set and during filming.
"We then went through an inspection with the costume department where our own personal wedding outfits and accessories were checked along with our makeup."
Ms Brennan said before filming day, they were notified of what colours they could or could not wear.
"We had to follow the guidance of what colors the movie producers and director wanted on camera," she said.
"Some items of clothing like stripe and check patterns do not show well on film. They wanted us all in slightly different selected colours.

"What you turned up in and once approved you had to wear everything identical for the two days, right down to exact jewellery and handbags."
Ms Brennan said it was "amazing" to see the wedding set.
"It was in an outside barn, hayshed setting with all tables set up decorated," she said.
"There was a huge crane like apparatus with a camera on it and other structures for lighting effects, sound etc.. it was just amazing to see."
Ms Brennan said there were so many people on the set, including stars such as Sam Neil who played Paddy Payne and Therese Palmer who played Michelle Payne.
"As well as producers and the director of the movie Rachel Griffiths," she said.
"You really had to pinch yourself to take it all in, we were really on a movie set.
"We had been briefed prior to coming on set not to harass any actors re autographs etc... Everything was so professional."
Ms Brennan said she wasn't sure how many takes it took for each section of filming, but "it was a lot".
"In between scenes and takes we had directing assistants running in and out putting warm coats and blankets on us for a minute or two then straight off ready for the next shot, as well as adjusting any jewellery that had moved on us," she said.
"It was two very long days but well worth the chance in a lifetime experience, a highlight for me was meeting both Sam Neil briefly and Therese Palmer but especially meeting director and Hollywood actress Rachel Griffiths and getting a photo with her.
"Not to mention all the wonderful people on and off the set."
Ms Brennan said both her and her mother were offered extra filming days at Flemington, Melbourne, but they felt it was just "too much".
"We both have a real appreciation of how long the hours are and the actors definitely earn their pay that's for sure," Ms Brennan said.
"We were lucky enough to get an invite to see the premiere of the movie at the Jam Factory in South Yarra.
"This was the very first time we had seen the finished product, so had no idea if any of us would be shown in the film, even for a second or two.
"We also received a movie ticket each from Transmission films for being a part of the movie, all extras received this for us to see movie at our leisure."
Ms Brennan said she was delighted when she spotted herself, and her mother in the film.
"If you look during the wedding speeches with Sam Neil, we are sitting directly behind Stevie Payne and also seeing the bride and groom off on their honeymoon," she said.
"It's amazing how much film is edited out for a final copy. It takes hours to get that perfect bit their looking for, to get the ultimate finish."
Ms Brennan encouraged people to go along and watch the movie.
"It is amazing. Rachel Griffiths and team have done a great job covering Michelle's life story," she said.
"All l can say is take some tissues, it's a wonderful movie and true story of a brilliant young woman, her beautiful brother Stevie Payne, who is a star and her wonderful battling family.
"I will be forever grateful for the opportunity of a lifetime to be a part of this wonderful film and to share the experience with my mother, something we will both share forever together."
