"There's some splendor, but a whole lot of warfare in the grass, in A Bugs Life, the latest computer-generated insect film of the year. Did I ever think I'd ever say that sentence? And who ever thought we'd get two in one year?"This page is a list of similar works made during the same period of time. Sometimes one work intentionally copied another. Sometimes it's part of a wider trend in which that type of work became very popular all of sudden and others are made. Sometimes it's total coincidence: the creators just had the same idea. Which is the original and which is the imitation is not always completely clear; sometimes, however, it is painfully so. Sometimes, rather than home-brew a knock off, a company will license a foreign work, and adapt it to be more like its competitor. Occasionally, creators will be forced to war with one another when they simultaneously produce similar works which are subsequently released within a short time from each other. One thing to remember regarding Dueling Works is that Tropes Are Not Bad — while many Dueling Works appear to be blatant rip-offs, the competition between two shows (or simply the desire to set each other apart) often spurs each other to develop in quality. The result is a grateful television audience. See also Dueling Products for proof that this type of competition isn't limited to just works. See also The Mockbuster. Not to be confused with Dueling-Stars Movie. Again, just to be clear: The works have to be produced during the same time period, otherwise you've got either Follow the Leader or Serial Numbers Filed Off. Also see Fandom Rivalry.
