a, in 1906. There’s no general consensus, however, about what the first film franchise was. Possibly “Bulldog Drummond,” or “The Lone Wolf,” or maybe “Godzilla?”

Regardless of where you stand on the first franchise debate, basically everyone can agree on this: studios love nothing more than to turn a hit film into a full-blown series. It turns out, there’s good reason for this franchise affinity. Joe Pasqualichio, an analyst at Citadel, explained it simply, saying: “Box office flops are going to come up from time to time, but your big bets, and especially the ones with IP backing them, should be enough to cover them. And that’s why you’re seeing studios move towards IP and franchise films…Today, more than ever we’re seeing this blockbuster strategy at studios where they rely on really big, tent-pole films—like the ‘Star Wars’ movies—to generate sufficient profits that cover all of the misses and make the overall slate profitable.” In the end, it all comes down to money.

But that doesn’t mean that every installment in a given series is a hit. In fact, nearly every great franchise has had a flop or two.
