Emergency Call (1952)

It's quite tough to be objective about this - it is a well made feel-good film with a worthy cause and sterling efforts from all concerned as they try to track down a blood donor who can save the life of a desperately ill child. Simultaneously, the police - Jack Warner and Bruce Seton - are on the trail of a dodgy boxing promoter who is trying to manipulate the career of "Tim Mahoney" (former World Light Heavyweight Champ Freddie Mills) and also of some other recalcitrant miscreants. It's got the smallest of budgets, but a surprisingly solid cast of British stalwarts from Dandy Nicholls and Anthony Steel - the well meaning doctor - to Sid James, Thora Hird and Eric Pohlmann and they all combine to make this a perfectly watchable tug at the heart strings mixed in with the usual detective yarn. If you come across it, then you ought to spare it 90 minutes - you'll feel better afterwards.
