Did 'Town and Country' kill Warren Beatty's acting career?

He's a notorious perfectionist on both the movies he directs and (to the grief of his directors) on those he only acts in. For someone of his longevity and stature, he's made very few films, reflecting his extreme pickiness at choosing projects. I doubt "Town & Country" "killed" his acting career--the last time he was an actual box-office star was probably 1978's "Heaven Can Wait"--so much as it reinforced his disinterest in acting in projects he didn't have complete control over. Then probably worries about age as well as his usual skittishness toward committing to a film led him to stall and stall and stall until he was de facto retired. A pity his intelligence was always so cautious in terms of making industry decisions--he could have been a major American director. Certainly "Reds" and "Bulworth" are more inspired and risky in terms of both subject and style than anything fellow actor-turned-director Clint Eastwood has ever done.
