Imagine Matthew McConoughey in Titanic or Russell Crowe in Wolverine; it sounds impossible to think about these actors in those roles. But the noticeable part here is that these movies had first been offered to them but they could not do it for one reason or the other. It came out as a pleasant surprise for the actors who acted in the movies later. Now, Matthew McConoughey would be feeling weird about having left out the offer. However, it is too late now and the role suited to the other actors very well.
