Maggie Smith Signs On for Another Season of 'Downton Abbey' TVLine

Maggie Smith has signed on for the fourth season of the PBS period drama "Downton Abbey," reports

Smith, who plays the Dowager Countess on the show, wasn't considered a lock for returning to the series, with "Abbey" creator Julian Fellowes saying last summer that he wasn't sure she would return.

Executive producer Gareth Neame confirmed her return at a post-Golden Globes party, the story says.

As previously reported, star Dan Stevens, who plays Matthew Crawley, won't be returning for the fourth season.
