An atheist who gained worldwide fame when he sued an Italian priest, claiming Jesus Christ never actually existed, has been fined by an appeals court in Rome for bringing a fraudulent suit … Cascioli, a retired agronomist, contended Righi violated a law that forbids deceiving the public. The atheist said the priest, who had publicly criticized him for casting doubt on the truth of the gospels, had no evidence Jesus ever existed. (Full article: WorldNetDaily)

It seems that a current trend among the scholarly marginal is to claim that Jesus never existed. That is the hypothesis of the recent film "The God Who Wasn't There" (which has been refuted in brief here, and also refuted in a much more indepth response here).

The fact of the matter is that hardly anyone believes Jesus never existed; that is the reason that "The God Who Wasn't" film has failed to attract any scholarly attention. Besides the many different authors who independently composed the New Testament documents, we have early atestation from the likes of non-Christian historians such as Tacitus and Josephus. For more information on this topic see "Is The New Testament Reliable? 2nd Ed." by Paul Barnett, the best general-audience work I know of on the subject of New Testament reliability, which also includes a summary of much of the early evidence that confirms Jesus' existence.
