He is best known for his roles in critically acclaimed movies such as The Florida Project, Get Out and Three Billboards Outside Ebbing, Missouri. 

And Caleb Landry Jones was very much the leading man on Saturday as he cut a striking figure while attending the Nitram photocall at the Cannes Film Festival.

The American actor, 31, stood out in a red and white pinstripe suit as he posed alongside the film's director and producer.

Caleb teamed his eye-catching blazer and trousers combo with a black shirt, white waistcoat and Shiko Tani Filamt e Ri black shoes. 

He appeared in good spirits as he posed on the blue carpet and waved to crowds at the event. 

The star posed alongside the film's director Justin Kurzel for several photos.

While Caleb was also pictured with screenwriter Shaun Grant and producer Nick Batzias at the event. 

The film Nitram is centred on the life of Port Arthur mass murderer Martin Bryant, with the title being Martin's named spelt backwards. 

Caleb plays the role of the lone gunman responsible for Australia's worst massacre on April 28, 1996, which took the lives of 35 innocent adults and children. 

Due to the sensitive subject nature of the movie, producers chose to film in Victoria instead of Tasmania where the tragedy occurred, the reported at the time of production in November.

The film will not depict the killings, but will instead focus on Bryant's life before his murderous rampage in an attempt to understand how the atrocity occurred. 

The publication also reported that the film will not name Byrant, and will also assign fictional names to other key characters. 

Australian stars Judy Davis, 66, and Anthony LaPaglia, 62, took on the role of Bryant's parents.

Actress Essie Davis, 51, portrayed Tattersalls lottery heiress Helen Harvey, who was a companion of Martin's.
