(Cover) - EN Showbiz - Sandra Bullock admits it could be years before she works with Ryan Reynolds again.

Last year it was revealed the Oscar-winning actress was keen to reunite with her The Proposal co-star, after the pair received rave reviews for their performance in the romantic comedy. It was reported Sandra and Ryan had agreed to appear in The Wanted, an action comedy which was scheduled to begin shooting at the end of 2010.

However, Sandra says a start date for the project is still to be confirmed.

"Who knows," she replied to E! Online when asked about plans for Most Wanted. "That could be eight years down the line. I have no idea."

In the movie which is being written by Peter Chiarelli, who penned The Proposal - Sandra will play a criminal suspect who is escorted to court by an FBI agent, played by Ryan. However, the pair are forced to go on the run after they are ambushed and end up falling for each other.

Sandra is confident the movie will still go ahead, and has urged cinemagoers to be patient as the finished product will be worth the wait.

"It's something in development," she added. "Don't you want it to be good? Let's find something good and then we'll do it." (C) Cover Media
