Step Brothers crowns box office

Will Ferrell's latest comic caper Step Brothers has made its debut in the UK and Ireland box office at number one.

The film, which tells the tale of two adult brothers brought together by an unexpected marriage, was followed by Mamma Mia! at number two.

Horror flick The Strangers and sci-fi film Babylon AD were the other new entries at numbers three and seven.

Last week's chart-topper, Hellboy II: The Golden Army, fell to number four, with The Dark Knight at five.
