I'm very skeptical. I fear that whoever they get to play Han Solo will make no attempt to capture Harrison Ford's mannerism, et. al. In fact, that's why I wasn't thrilled with Chris Pine's James T. Kirk. Pine made his own character and that's fine, but to me it just wasn't Captain Kirk.

I think a good example of how to do this right is the recent Back to the Future adventure game. Michael J. Fox wasn't available so they got a damn good soundalike, and it worked quite well. It wasn't 100%, but it felt like a pretty organic continuation. If there's going to be a Han Solo film, that's the way I hope they go. :)
