Regarding Harrison Ford... Though I can't say much for movies like Firewall, I would say that I LOVE LOVE LOVE Six Days Seven Nights. It's a charming romance adventure and Ford gives one of his very best performances here. It's weird, of course, to see the chemistry with Anne Heche, though less so (I guess) with the passage of time. She's pretty good too.
So, I would say give that one a shot. It's an overlooked DVD pick!!!
