SAN DIEGO --  Just when it seemed like it was official, Jessica Biel say fans should hold their horses about her potential role as Viper in the forthcoming "Wolverine" movie.

"People keep talking about this," a shocked Biel explained to HitFix during our interview at Comic-Con. On Friday (July 14), News had spread like wildfire at Con that the "Total Recall" actress had signed on the bottom line for Viper. "I don't know anything about it. It's a little bit too soon for that kind of an announcement. I'm excited about this series..."

But it's not a done deal.

"I love wolverine, Hugh Jackman is so cool... people are surprising me about it all the time," she said about fans' reaction to the false start. "When you see that people acturally really think that could be an amazing character... when other people are excited about things."
