It was found that a sequel title influences its popularity. This research was carried out by scientists from University of California and University of Pennsylvania.

It is traditionally considered, that if the sequel title (for example, ” Matrix-2″) is similar to the title of the popular film-original (for example, “Matrix”), spectators are inclined to consider, that continuation, at least, is does not concede to the original. However it is not true. The analyse of some films which gave birth to their sequels found out that the sequel should possess individuality. In other words, it should be titled not “Matrix-2″, but, for example, “Matrix-2. Reloaded”. Sequels, titled in such way, collect big cash and have longer “life” - the spectators continue to hire and buy film-holders and CDs with them longer. It is explained by that fact, that spectators are subconsciously convinced that films with identical titles are extremely similar, therefore it is not necessarily to see them.

The average cost of a conclusion to the market of the Hollywood film in 2004 was $100 million. That is why studios began too make more sequels expecting to use commercial potential of the previous films.
