Ryan Reynolds reported to work yesterday on the New Orleans set of Green Lantern, where he was covered in motion capture sensors that will help his superhero costume come to life on the big screen. One place that didn't need any digital enhancement was his impressive arms, which Ryan's been toning through trips to the gym with wife Scarlett Johansson. There was no sign of his costar Blake Lively, but her pup Penny was running around between takes. Elsewhere in the Louisiana city, his friend, The Proposal costar and fellow MTV Movie Award Best Kiss nominee, Sandra Bullock, is spending time with her son, Louis. Sandra and Ryan also share the honor of being in the Final Four of the PopSugar 100, though she's the one currently in the lead. We're in the final stretch before the tournament is down to just two, so make sure to fill out your ballot and enter to win a Chanel bag!
