Two reasons. First, understand that the chief modes of entertainment for many Hollywood viewers are playing video games and watching half-hour television sitcoms. Thus most of these people have regrettably short attention spans. This makes it difficult for them to read a newspaper or book, much less concentrate for more than ninety minutes on a film! Now, add in multiple plots and characters, as most of Bollywood's masala films do, and you'll have completely lost them! Realizing this, Hollywood directors like to keep their films very simple. They usually stick to two plots at the most. Unrelated comedy subplots (such as those helmed by Johnny Lever in Bollywood films) as well as dance numbers that do not advance the narrative are strictly frowned upon. They distract viewers who are trying to keep track of the main story. They're just too confusing.

Second, it appears that although Hollywood directors enjoy film budgets far larger than those of Bollywood, they lack the canny financial sense exhibited by our favorite desi directors. (Hollywood fans who monitor trade papers know this; they're constantly reading articles about how such-and-such director is running way over budget!) So, although the wardrobes seen in Hollywood films are not nearly as beautiful and ornate as those used in Bollywood films -- and despite the fact that the shooting locations for Hollywood films are usually confined to just one country, rather than switching between, say, America and Switzerland and Austria -- they still cannot manage to stay within budget! Thus they cannot afford to make longer films.
