Taking £2.5 million from the weekend the film which had a massive budget and is set to start a new series of films was expected to smash its way into the box office from studio Warner Bros.
For the director this is below the debut of his top grossing films the Sherlock Holmes movies starring Robert Downey Jnr. which both debuted in the £3 million mark.
Falling into second place is Alien: Covenant which only just missed out on spending a second week at the top with a weekend gross of £2.1 million.
This brings the films total gross to £10 million, Prometheus at this point in its run was doing very similar business so expect this to end its run with a similar £20 million+.
Also new this week is Snatched starring Amy Schumer and Goldie Hawn at number 4 with a debut of £842,000 and Colossal starring Anne Hathaway at number 9 with £150,000.
