Civil War now makes it three weeks at the top and this week adds £2.7 million to its gross which has now soared to £32.1 million.
The film is now the 5th highest grossing of the year and before it finishes its run it should beat Batman V Superman Dawn of Justice and Deadpool, currently at 4 and 3 respectively.
The Angry Birds Movie is the highest new film at number 2 which on its debut takes £2.1 million.
Aiming squarely at kids but also appealing to adults that hooked on the game the film loosely follows the plot of the games.
The film should do well over the coming half term but will have limited appeal after that.
Longest stay by a film on the box office this week is Zootopia with 8 weeks and the highest grossing movie is The Jungle Book at £39.3 million after 5 weeks.
