Liam Hemsworth on The Hunger Games Opening Day Pictures

Liam Hemsworth and his costars Amandla Stenberg and Alexander Ludwig stopped by the Barnes & Noble at The Grove shopping mall in LA last night to sign copies of The Hunger Games. The trio were on hand for the fan event just hours before the first midnight showings of the film began. The movie is already projected to make about $130 million in its opening weekend, with the 12 a.m. screenings already raking in about $20 million.

The cast of the big-screen adaptation of the bestselling book has been hard at work promoting the release of the movie for months. This week, Jennifer Lawrence made several late-night and early-morning TV stops, visiting GMA, Late Night With Jimmy Fallon, and The Late Show, just to name a few. Check out our review of The Hunger Games and, if you were one of those who stayed up late to see a midnight screening, tell us what you thought of the film in the comments!
