Leonardo has made a large but unspecified donation to UNICEF for tsunami relief efforts in Thailand, where he spent four months shooting the 2000 movie The Beach.

Edge of Darkness, based on the 1985 Brit TV drama about a cop searching for his daughter's killers, bears a resemblance to last year's Liam Neeson hit Taken.

Over the last several months, I've caught bits of Taken, Hostel II and Brokedown Palace on cable. This naturally got me thinking about personal safety on the road.
