Neill Blomkamp this week scores his second number 1 film with his second film, Elysium, which smashes last weeks top film from the top spot, We're the Millers and The Mortal Instruments also debut in the top 5.

With a weekend gross of £3.1 million Elysium easily takes over at the top of the UK box office making it the 21st number 1 film this year.

Following behind in the runner up spot is We're the Millers.

Last weeks top film, Kick-Ass 2, falls all the way to number 7 this week with a weekend take of just over £600,000.

Compared to my predictions Elysium did open in the top spot and was just shy of my £4 million suggestion. We're the Millers opened where I suggested at 2 and was just a little shy of the £2 million I predicted. The Mortal Instruments performed as I expected opening in the top 5 and with around £1 million. Lovelace opened well outside the top 15 (20) and only took £86,000, it was only in 80 cinemas though.

Last year Brave contunued to perform well in the top spot with the highest new film right down at 5 being Keith Lemon: The Movie.

5 years ago Hellboy II debuted at number 1 knocking The Dark Knight down to number 4.

10 years ago American Pie: The Wedding remained at the top with Lara Croft Tomb Raider: The Cradle of Life debuting at 3 as the highest new film.

15 years ago The X-Files movie took over at the top on it's debut weekend taking over from Armageddon which fell to number 2.

Four main new releases should battle for attention at cinemas in the UK this weekend with Matt Damon and Jodie Foster leading the way but Jennifer Anniston not too far behind.

From the director Neill Blomkamp who brought us the critically acclaimed South African film District 9 back in 2009 comes his follow up. This time he hits Hollywood getting Damon and Foster involved.

The film has been received well by critics and Blomkamp has again used sci-fi to �hide� a political message.

I expect Elysium to debut at the top of the box office over the weekend with nothing else to challenge, expect a debut in the region of £4 million.

Were the Millers starring Jennifer Anniston will challenge Elysium for the top spot. The wacky comedy has had surprisingly good reviews especially for Aniston.

The friends actress is always a big pull in the UK but the film doesn't have the special effects spectacle that will wow on the big screen, I expect a debut in the region of £2 million and probably debut at 2.

Also out this week is The Mortal Instruments: City of Bones have which will probably do better than I'm expect, becoming a teen favourite and having a cult following this will appeal to the Harry Potter and Twilight audience and could do big numbers, I'm expecting somewhere around the £1 million mark and a top 5 entry. Finally this week is Lovelace, starring Amanda Seyfried as fames 70's porn actress Linda Lovelace. Lovelace will debut in the top 10 but I'm expecting under a £1 million debut.
