Iron Man holds on to UK top spot

Iron Man sees Robert Downey Jr make a comeback as an action hero

Comic-book film Iron Man has topped the UK and Ireland box office chart for a second week running.

The movie, starring Robert Downey Jr and Gwyneth Paltrow, took £1.98m, bringing its two-week total to £10.2m.

Cameron Diaz's romantic comedy What Happens in Vegas was the highest new entry at number two, with £1.3m.

Forgetting Sarah Marshall fell a place to three, while adventure movie Speed Racer entered the chart at four after taking a disappointing £362,000.

Family film Nim's Island dropped from number three to number five.

British horror Doomsday was a new entry at six with Patrick Dempsey's Made of Honour down three places to seven.

Black comedy In Bruges, gambling drama 21 and horror film The Eye made up the rest of the top 10.

Meanwhile in a new development on the North American box office chart, Speed Racer fell to third place after film studios over-estimated its success by $1.6m (£820,000).

Initial forecasts placed the film in second place after its opening weekend on $20.2m (£10.4m), but final figures revised this total to $18.6m (£9.5m).

The film - made by the Wachowski brothers, best-known for The Matrix franchise - cost $120m (£61.6m) to make.

Going into the weekend, Speed Racer had been the best hope of film studio Warner Bros of giving Iron Man, the current box office champion, a run for its money.

The change pushed What Happens in Vegas into second place after taking $20.2m (£10.4m), slightly above its original estimate.
