Comic book blockbuster Iron Man 3 has become the fifth top-grossing film of all time, according to online movie tracker Box Office Mojo. The sequel, which has now made $1.14bn (£760.5m) worldwide, overtook 2011’s Transformers: Dark of the Moon to claim fifth place in the chart. Avatar and Titanic remain the all-time box-office champs, having both grossed more than $2bn (£1.32bn) worldwide. Avengers Assemble and the final Harry Potter are ranked third and fourth. Iron Man 3, which opened in the UK in April and in the US in May, is the fourth film to feature Robert Downey Jr’s metal-clad crime-fighter. The third was 2012’s Avengers Assemble, known in the US as The Avengers, whose current worldwide box office tally stands at $1.51bn (£1bn).
