Disney is among those girding up “Gulliver’s Travels” again for the big guy to show both his forte and fun with Lilliputians.

Having launched the legiter at the U-Amphi, McAnuff and producer Marvin Worth have again locked ‘emselves into solitary, nights and days, Sundays too, working on the script of the James Dean biopic — since writer Israel Horovitz is away in Europe and WB wants a quick start.

While Paul Alexander’s “Boulevard of Broken Dreams, The Life, Times and Legend of James Dean” (Viking) deals explicitly with Dean’s homosexuality, the movie script, says producer Worth, “infers” but doesn’t dwell on it.
