The teenage stars of new Irish crime caper The Young Offenders have said that here was immediate rivalry between the pair when they first met during auditions for the film. 

Newcomers Alex Murphy and Chris Walley play Leeside chancers Conor in the comedy, which is based around the record seizure of €440m of cocaine off the west Cork coast in 2007.

Bike thief Jock (Walley) senses an opportunity and ropes his even-more-impressionable best pal Conor (Murphy) into a plan to cycle down to the crime scene to find a missing bale of drugs

Written and directed by Peter Foott, who made the video for The Rubberbandits' Horse Outside, the film was the joint winner at the Galway Film Fleadh alongside A Date for Mad Mary.

Speaking to RTÉ Entertainment, Murphy revealed that there was immediate rivalry when he first met his co-star Walley. "My mum had to be with me for all the auditions because I was 17," he said. "Me and Chris went into the second round of auditions and that's where I met Chris. I told my mum before I went in, he's the competition."

Walley added: "Helen, Alex's mum, is lovely but the first time I met them they didn't say a word to me! We were both going for the same part and what made it worse was not only were they not talking to me, but they were sitting there whispering to each other! I found out later that he was just playing mind games with me."

The actors both hail from Cork but were encouraged by director Foott to go all out with the strongest Leeside brogue possible and Walley says they listened to a lot of songs by Cork rapper Bony to perfect their accents.

Murphy also said it was a pleasure to work with co-star, comedian PJ Gallagher. "I love PJ. He's a nutter!" he said. "He's a lovely face but he's also intimidating. We were cracking up all the time with him." 

The Young Offenders is released nationwide on Friday, September 16. Read our review here.
