Clearly exhausted from their earlier morning-show rendezvous with Brian Williams, Righteous Kill co-stars Robert De Niro and Al Pacino last night indulged David Letterman with one final on-camera tryst before returning to the anonymity of their respective solo careers. And what a fitting send-off, with the pair teaming up on the "Top 10 Reasons I Like Being an Actor" — a droll bit of thanksgiving that still won't make us forget Heat, but may yet be proven our lone cultural reward for tolerating the existence of Righteous Kill at all. See what kind of magic is possible when less than 12 producers are involved? Next time, guys, next time. [CBS]
