You might think that two-time Oscar-winner Dustin Hoffman has done pretty much everything in his prolific career, but his upcoming film, Quartet, will be his directorial debut.  Centering on a nursing home for retired opera singers, Quartet shows that not everyone ages gracefully as the egos of a few threaten to disrupt plans for the home's annual concert.  But the show must go on!

Quartet stars Maggie Smith, Billy Connolly, Pauline Collins, Tom Courtenay and Michael Gambon opens domestically in limited release on December 28th and in the U.K. on January 4th 2013.  Hit the jump to watch the trailer and clip.

Here’s the official synopsis for Quartet:

Lifelong friends Wilf and Reggie, together with former colleague Cissy, are residents of Beecham House, a home for retired opera singers. Every year on Giuseppe Verdi’s birthday, the residents unite to give a concert to raise funds for their home. But when Jean Horton, a former grande dame of the opera fallen on hard times, also Reggie’s ex-wife and the fourth and most celebrated member of their former quartet, moves into the home to everyone’s surprise, the plans for this year’s concert start to unravel.

As old grudges threaten to undermine past glories and theatrical temperaments play havoc with the rehearsal schedule, it becomes apparent that having four of the finest singers in English operatic history under one roof offers no guarantee that the show will go on.
