A romantic and sentimental comedy set at the turn of the 19th century, An Ideal Husband delves into themes of love, passion, and betrayal among the aristocracy. Sir Robert Chiltern (Jeremy Northam), a brilliant politician and a perfect gentleman, is the ideal husband for the charming Lady Chiltern (Cate Blanchett). They have a widely envied marriage until charming Mrs. Cheveley (Julianne Moore) appears with the intention of revealing a dark secret from Chiltern's past. When his world seems to be falling apart, Chiltern turns to his lifelong friend Lord Arthur Goring (Rupert Everett), the most eligible bachelor in town. Goring soon finds himself caught up in a web of lies, temptations, and secret liaisons. Furthermore, the persistent charms of Sir Robert's sister Mabel (Minnie Driver) are becoming a serious threat to his much-cherished bachelorhood. Using political intrigue and clever wit, An Ideal Husband draws a picture of a society struggling with issues still valid today.
