I don't know about you, but I just couldn't see Warren Beatty playing Richard Nixon. Fortunately he won't be, but for some reason he was almost cast as the former U.S. President in Ron Howard's next project, Frost/Nixon. If you think it would have been a good idea, then maybe you should write up a script about the Nixon and Kennedy debates -- and if you get Beatty to play Tricky Dick, then maybe you can get Leonardo DiCaprio to play JFK.
Apparently now that Beatty is no longer in talks for Howard's film, which you may recall is based on the play by Peter Morgan, a more proper choice for the role is being considered. Frank Langella, who played the part on stage, is in negotiations to reprise his performance for the screen. The casting of Langella will certainly make more sense than the casting of Beatty, because the play's other star, Michael Sheen, has also been in talks to reprise his own role, as television interviewer David Frost.
Langella should have been considered from the beginning, but obviously he isn't a big enough star for Hollywood to think of right away, despite all the acclaim he received for his work in the play. So as payback, I hope the actor, who long, long ago was nominated for a Golden Globe for Most Promising Newcomer (he lost to James Earl Jones), not only gets the part, but also wins some awards for playing it. I'm surprised that Hollywood still continues to pass over great stage actors for more well-known names when a play is turned into a film. They should have learned 40 years ago with the whole Julie Andrews-My Fair Ladything.
