"Lost" Star, Neil Hopkins Talks Basketball, SportsCenter, and His Apprication For The Ladies Who Know The Game...

GG: Lost  is filming during the NBA playoffs and opening of baseball season. Do you have any time to sit down and watch a game? Are any of your fellow cast members following the playoffs? Who, and what teams do they follow?

NH: "Well, they finished shooting at the end of April, I believe, so the majority of the NBA playoffs didn't conflict with shooting too much. I've had time to watch a few games, but I'm so busy that I usually don't really start watching all the games until the Conference Finals. I usually check out highlights on SportsCenter or NBA.com.
And I can't really speak for the rest of the cast, because I've really only spent large amounts of time filming with Dominic Monaghan, but he's a huge Manchester United fan. Wears the jersey around and everything"
