To cheat or not to cheat...

Really, there is no question. Cinema loves infidelity. It's the scenario that can bring about sex, anger or comedy. Think the passions of 'Unfaithful,' the dangers of 'Fatal Attraction' or Leslie Mann's paranoia in 'Knocked Up.' It fuels reminiscences in 'The End of the Affair,' is an unavoidable downside to soulmates in 'Before Sunset' and inspires men to murder in 'Dial M for Murder.'

This month, it's also a prevalent theme in new releases. As Perri noted last week, the first month of the year usually isn't the best for cinema. It's plagued with studio runoff as everyone focuses on last year's picks and who will win all of those pretty little statuettes. This year, however, is a little bit different, fodder fare mixed with Golden Globe-nominated productions. But it's also heavily unfaithful.

Out of twelve main releases, four focus on cheating. We've got 'Country Strong,' 'The Other Woman,' 'Barney's Version' and 'The Dilemma.' 33% of January's films in the first half of the month center on lusty desires and unfaithful actions.
