With a gross of £69,130,014 it out grossed the number 2 film by nearly £20 million. Even more remarkable is that Mamma Mia! has now become the biggest film in the UK, topping Titanic's 10 year reign.
Sliding nicely into the runner up spot for the year is the Bond film Quantum of Solace with a UK gross of £50,405,045. Although a good gross the studio may see this as a little disappointing as the last Bond film, Casino Royale, tool £5 million more.
Third on the list is The Dark Knight with £48,685,166, many thought this might have come out on top, but clearly few realised the power of the chick flick during the year.
All three of the top films of the year are in fact still showing in cinemas across the country, despite 2 of them being available on DVD/Blu-ray already.
The rest of the top films of the year are filled by the like of Indiana Jones And The Kingdom Of The Crystal Skull at 4, Sex and the City: The Movie at 5, High School Musical 3 at 7 and Wall-E at 8.
