I've recently purchased a DVD which features a movie about rugby league. It's a comedy drama so you could liken it's tone to a film like "Brassed Off".
It's called "Footy Legends" and can be purchased from a place called DVD Orchard in Australia.

Please make sure that your DVD player is multi regional as the DVD is region 4.
It even features a Wigan legend, Brett Kenny and another former Wigan player, Matty Johns.
