Dailies | Marriage Struggles to Stand a Short Test of Time in ‘I Give It a Year’ Trailer (Video)

Rose Byrne and Rafe Spall star as a married British couple facing temptation from Simon Baker and Anna Faris shortly after tying the knot

A new comedy from "Borat" and "Bruno" writer Dan Mazer is named after a common expression uttered when young couples rush into marriage too soon.

"I Give It a Year" follows a couple, played by Rose Byrne and Rafe Spall, who get married after just seven months of knowing one another, and every one around them thinks they're a little bit crazy for doing so.

Simon Baker ("The Mentalist") and Anna Faris ("Scary Movie") appear in the British comedy as adulterous temptations, while Minnie Driver co-stars as Byrne's sister and Stephen Merchant turns terrible jokes into zingers as the groom's brother.

"Fornication," Merchant says to start off a wedding toast. "I'll read that again. For an occasion..like this."

Mazer's directorial debut exploring the trials and tribulations of marriage hits U.S. theaters Aug. 9. Watch the trailer, below:
