Actor Alec Baldwin is convinced the days of veteran Hollywood stars landing top movie roles are over, insisting most actors will have a short career.

The 30 Rock star appears in new documentary Seduced and Abandoned, which centres around the efforts of Baldwin, Neve Campbell and director James Toback to find financing for a new film.

Their attempts are hindered by suspicions their careers are over, and Baldwin is adamant most modern movie stars are destined to suffer the same fate.

He tells Britian's Radar magazine, "The day in which you can be James Stewart or Henry Fonda (has passed), having careers like that is very tough. The only one I see having that now is Tom Hanks. His relationship with his audience is so durable, he will be making films for 50 years, for everyone else, you realise you have a shelf life."
