Delivery Man

Vince Vaughn stars as David, a butcher's van driver whose past catches up with him in director Ken Scott's Hollywood remake of his own serio-comic Canadian offering Starbuck. That was the nickname David used during his frequent visits to a sperm bank in his cash-strapped youth, but now he finds he's the biological father of 533 children, 142 of whom have joined in a lawsuit to reveal his identity. Unsure he's actually parent material, David conspires with his lawyer (Chris Pratt, funnier than the clunky script) to surreptitiously track down some of these grown-up kids who've never known their "dad" - and the emotional complications escalate from there. The results are mildly diverting, as eternal man-child David stumbles out of his comfort-zone, but outright belly laughs are in short supply, and the storytelling lacks the depth for its theme - about the responsibilities and rewards of parenthood - to hit home. It's warm-hearted, certainly, but ultimately undone by a would-be feel-good central conceit that makes less and less sense the more you think about it.
