After 2 weeks at the top Lucy gets knocked down the chart by Sex Tape which makes it's debut in the Uk at number 1.

Starring Cameron Diaz and Jason Segel this Jake Kasdan directed comedy about a couple trying to spice up their sex life by making a movie, which then gets shared to everyone debuts with £1.4 million.

Not a great opening gross especially for the 2 leads, Diaz has enjoyed great success with the Shrek franchise while Segel has seen big grosses with the likes of The Muppets, Gullivers Travels and Knocked Up.

Lucy has been having a great cinema run and after 3 weeks of release has taken a very respectable £10.46 million.

Also new this week is

Before I go to Sleep at 3 - The Hundred Foot Journey at 4 - The Guest at 8

Chart History - One year ago this week Richard Curtis's About Time made it's debut at the top of the box office knocking the One Direction boys to 3rd.

Five years ago District 9 was the debut film for Neill Blomkamp and it debuted at the top knocking The Final Destination into second.

Ten years ago Steven Spielberg and Tom Hanks team up agin to debut the Terminal at the top knocking Dodgeball to second place.

Fifteen years ago so a very static box office with South Park Bigger Louder and Uncut staying at the top while the top new film was Go right down at six.

Finally twenty years ago this month Speed and Forest Gump where the big film at the box office while twenty five years ago Dead Poets Society and Young Einstein were the big grossing films of September.

The UK movie goer this week kept Lucy starring Scarlett Johansson in the top position with a number of weaker new releases in the market.

The Luc Besson directed film took just under £2 million during it's second weekend of release and now sits with a total gross of £8 million.

Highest new entry of the week is the buddy cop comedy Lets Be Cops starring Damon Wayans Jr., as you'd expect from a film of this kind it's a slap stick comedy.

Lets Be Cops takes £1.6 million for the weekend, but I suspect it may sink and disappear from the box office quickly.

Other new films to hit the box office this week are - Sin City A Dame To Kill For at 4 (with previews grosses) - If I Stay at 6 - the new Daniel Radcliffe so maybe a little disappointing - As Above so Below at 8 - Million Dollar Arm at 15

A year ago this week One Direction This is Us took the top slot on it's debut weekend of release pushing Elysium to 2.

Five years ago The Final Destination took the top of the box office on it's first weekend taking over from Inglourious Basterds.

Ten years ago Dodgeball entered the chart at the top and knocked The Village down to 2 after it's single week at the top.
