Definitely noticed :P I knew that Marsha Thomason looked familiar but I couldn't place her so I had to look it up, but the moment I saw Sonya Walger I was like, "Penneh!!!!"
I watched a few minutes of this last night, and I noticed immediately that they are both on Lost. I seem to keep watching movies where lots of Losties show up. This movie also has Marl Pellegrino who plays Jacob on Lost. So 3 actors total...
