Decorated Australian horse Winx to be formally honoured with movie documentary - with her incredible 33 consecutive wins - including 25 Group One races - a key focus in the film

Decorated Australian racehorse Winx will be honoured with a movie documentary which has successfully captured her extraordinary career.

'A Horse named Winx' tells the inspirational story of one of Australia's greatest sporting champions, who became a national treasure as she won 33 consecutive races.

Janine Hosking, the movie's director and producer, said bringing Winx's story to the silver screen has been a 'labour of love.'

'I remember my Mum [Lorna] told me one day 'you have to watch this amazing horse, Winx', who kept winning her races,' she told News Corp.

'From that moment, I became fascinated by the sheer juggernaut of Winx and her story.'

Hosking interviewed the likes of Winx's trainer Chris Waller, champion jockey Hugh Bowman, plus the mare's owners Debbie Kepitis, Peter and Patty Tighe - and all were on board in terms of a movie.

The film documents Winx from when she was an emerging foal to an eventual sporting phenomenon.

During Winx's reign, huge crowds descended on racetracks around Australia - including Royal Randwick and Flemington - to witness the Phar Lap of the modern era.

She managed to snare 33 consecutive wins, a record which will probably stand the test of time.

Winx nearly died when her first foal was stillborn, but she slowly recovered and eventually gave birth to a healthy filly by Pierro.

The filly was later sold for a staggering $10million at the Inglis Easter Sale in Sydney last month.

Previously, the sale record for a yearling filly was $5million for a half-brother to iconic racehorse Black Caviar in 2013.

Aside from her race record of 33 wins in a row - including a staggering 25 Group 1 victories - Winx also secured $26.4 million in prizemoney.

She also won a record four consecutive Cox Plates between 2015 and 2018.
