Redford was said to be directing for the longest time. Perhaps he is too beat from the last couple of films but why did he hand it over to the director of Big Miracle, Sister of the Traveling Pants and He's Just Not That Into You? Seems like a waste
Ken Kwapis also directed multiple episodes of TV shows like Malcolm in the Middle and The Office. I feel like the comedy style of this movie could have an Office-ish feel to it, so I'm not worried.
Are you equating script writing to directing? Just FYI, they are entirely two different things. Just because someone directs a film that isn't a genre of your liking doesn't say anything about their ability to direct. I assure you, Ken Kwapis is the greatest Director who ever lived. If you worked with him for 1 day, you would know this. Heck, if you worked with him for 1 hour, you would know this. He is FANTASTIC, and this film will be AMAZING!
