The Australian actor, who plays top jockey Damien Oliver in upcoming Aussie movie The Cup, said that he found the job difficult because he is not very confident around horses.
Curry told the Herald Sun: "The horses and I don't really get along, I'll be honest. They are wonderful, beautiful creatures, but so are great white sharks. I don't want to swim with them or be on them, I just want to bet on them.
"We had 500 extras on day one and I got bucked off in front of all of them. And my mum laughed the loudest. Thanks for that, Mum."
The Simon Wincer film tells the story of Oliver's Melbourne Cup victory on horse Media Puzzle shortly after the death of his brother Jason. Daniel MacPherson plays Jason, while former Home and Away actress Jodi Gordon plays Curry's on-screen partner.
On the subject of Gordon, Curry joked: "My brother [Bernard] was on Home and Away and played her boyfriend [Hugo Austin], and then she came over to The Cup and played my [partner]... I have two more brothers and she has a long career ahead of her."
Curry, who is also known for his roles in Cloudstreet and Neighbours, revealed earlier this year that he and girlfriend Naadein Crowe had got married after eloping to Bali.
The Cup is due for Australian release on October 13 this year.
