This week we finally see the full release of Transformers: Age of Extinction and How to Train Your Dragon 2, and predictable they dominate the upper end of the box office chart.

Taking the top spot is the 4th in the Transformers series of movies from director Michael. The film had previews last weekend and takes the number 1 position with ease this week grossing £11.7 million in the process, it is the biggest grossing opening weekend of the year so far.

It's interesting to note this opening gross does include the £8 million from last weeks preview screenings, a £3 - 4 million is a closer opening weekend figure.

Opening in second place after going on general release is How to Train Your Dragon 2 which also includes money from it's previews over the last 3 or 4 weeks.

Falling to third this week is last weeks top film Mrs. Brown's Boy's D'Movie which after 3 weeks has grossed £11.8 million.

There were a number of other new film this which included - Begin Again at 5 - Boyhood at 7 - Humpty Sharma Ki Dulhania at 12

Last year at the box office Monsters University opened at the top of the chart knocking Despicable Me 2 into second place after 2 weeks at the top.

Five years ago Sasha Baron Cohen opened at the top with Bruno which knocked Ice Age: Dawn of The Dinosaurs to second place.

Ten years ago Shrek 2 held on tight at the top for another week keeping Around the World in 80 Days in second place for it's debut.

Fifteen years ago there was little change at the top with The Mummy retaining it's lead for a second week, highest new film was 10 Things I Hate About You at 5.

An interesting weekend of releases, Transformers: Age of Extinction and How to Train Your Dragon 2 go on general release after a couple of weeks of previews, and Boyhood and Begin Again are fresh to cinemas.

The fourth Transformers film is going to be the top film of the weekend, last weeks previews will be added to the gross meaning it will open in the £10 million mark and it could be the biggest opening of the franchise.

How to Train Your Dragon 2 has been on pre-release for a while now and has been on the box office chart for a couple of weeks, it's wider release will push it up the chart and it should go to number 2 this weekend.

Boyhood is a film from Richard Linklater and has been 12 years in the making, following the life of a young lad Linklater film in realtime with the boy growing up. Good reviews means it should get at least a top 10 entry.

Also out is Keira Knightly and Mark Ruffalo in Begin Again.
