As it happens every summer, the blockbuster season is filled with film franchises returning to theaters with a new installment. While some franchises testing the waters with sequels — 21 Jump Street and How to Train Your Dragon both released follow ups in June — The Expendables is stepping into trilogy territory. Later this summer, the film will debut its threequel in theaters. But the question is, will it push forward with a fourth (Transformers) or seventh (Fast and Furious), or just stick with three?
The famed trilogy has worked out for a number of franchises, from the planned (Star Wars) to the “let’s just do it for fun” (Ocean’s). But how successful were all three films?

However it’s not the case for every franchise. We examined some of movie’s most beloved trilogies to figure out what was the peak installment.
