Although hard to pigeonhole, the picture unavoidably recalls the idiot-savant classic “Being There,” and significantly resembles “The World According to Garp” in tone.
Mixing elements of "Rain Man," "The World According to Garp" and Woody Allen's "Zelig," "Forrest Gump" covers 30 years in Gump's life, and reframes recent history by suggesting that one man can leave his stamp -- through blunders, serendipity and simple good will -- on several key historical moments.
That's the cinematic formula for "Forrest Gump," which combines the most interesting elements of "The World According to Garp," Woody Allen's "Zelig" and "Being There."
His direction is inspired, and he had the good idea of crafting the film into a series of mostly short scenes which really give you an overall view of T.S. Garp's unlikely life, somehow like in "Forrest Gump".
