StudioCanal UK would be a suitable distributor for the film "Dirty Riches" for three key reasons: 1) StudioCanal UK specializes in releasing British films, which is relevant as the film's target audience is in the UK. 2) It is an independent distributor, which would make negotiating a deal easier as an independent production company. 3) While it is a smaller distributor than major studios, the film has a national UK focus so StudioCanal's reach would be sufficient.
