Oh, I think Nathan Fillion is a much better replacement for Harrison Ford than Russell Crowe, but then I'm thinking of the 'Han Solo' part. ;o)
Oh would never think Crowe would replace Ford as far as Han Solo is concerned...I just joke about how Ford is no longer an actor I care to follow because I have been so impressed with what I have seen of Crowe's films (my personal jury is still out on the actor himself...not really sure I want to give it much thought, considering...) Ford however has gone all weird though...and an Indy 4? Puhleeez!! I can do without another Indy.
