Honestly, no idea. I do think Clancy missed a trick when he sold the rights, as they aren't doing a great job IMO.
Sum of All Fears was *ok*
Without Remorse.....well that one pisses me off even more. Its my favorite book and they really screwed it over. It was decent as a generic action movie, but awful as a telling of Kelly becoming Clark. I was even excited to see Michael B Jordan as Kelly, i thought that would really work. Just a shame the films story and writing was so generically crap.
I didn't even enjoy the Jack Ryan show that Amazon did. That crap movie with Chris Pine.....all the Rainbow 6 games bastardising the source material (except the original which was a purely tactical shooter)......what the hell was H.A.W.X. Ubisoft just slap Clancy's name on stuff in the hopes it sells.
