That's wonderful. Hope it's not a rumor. In the History Channel documentary on Howard Hughes, I could see his many characteristics that Jim would be the best person to bring forth, in my opinion. I so wished he could have been in the Aviator, but alas! Ofcourse Leo was good in it. But the one thing that I feel Leo didn't bring out was Hughes amiability, inspite of his reputation for being hard-nosed etc. etc. But then, people are complex and its difficult to do full justice in a depiction and Leo did his best. I do hope Jim does this, it's right up his alley.

While running day-to-day business operations, they also took great pains to follow Hughes' every bizarre whim. For example, Hughes took a liking to Baskin Robbins' banana-nut ice cream, and his aides were horror-stricken when they learned that Baskin-Robbins had eliminated the flavor. They made a special order of 350 gallons — the smallest amount the company could provide for a special order — and had it shipped from Los Angeles to Las Vegas. A few days after the order arrived, Hughes announced he'd tired of banana-nut and only wanted vanilla ice cream. For years afterwards, Hughes' aides gave free gallons of banana-nut ice cream to their friends and family.
