Just thought of something... Having Shatner in Star Trek XI could work! What if the powers-that-be and the s/fx company in charge of the production used the technique utilized in X-Men 3 that made Picard... er... Patrick Stewart look younger. If Shatner hit the running track and the exercise bike to loose weight, it would work! They would also have to do this with Nimoy as well. Perhaps the framing story could be a sequel to Star Trek VI. Whilst Kirk 'retires' from Command duty, and the Enterprise-A is mothballed, he could still be active in Starfleet, teaching at the Academy.
