If Bugs Bunny were to direct his signature inquiry--"What's up, doc?"--toward the modern-day Warner Bros. creative team, he wouldn't be far off. For 1001 Rabbit Tales, they've doctored up a batch of classic cartoons featuring the carrot muncher and his bumbling comrades and bundled them, near seamlessly, into a feature-length film. Here's the premise: Bugs and Daffy, both book salesmen, are competing to sell the most copies of a kids' book. Instead of burrowing a beeline to his sales territory (he should have made a left at Albuquerque), Bugs ends up in the castle of Yosemite Sam, here a harem-leading honcho. Sam's pain-in-the-spurs son, Prince Abalaba, needs somebody to read him stories; Bugs, who'd sooner take the job than suffer the alternative, that involving being boiled in oil, signs on.
