Question: How big is the National Park that the Yellowstone River flows northward through? Passage:The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.

Question: How many movies were directed byt the director of Beyond the Ocean? Passage:Gradually Clayburgh shifted into being more of a supporting character actress in the 90s, taking on roles as diverse as an antagonistic judge in Trial: The Price of Passion (1992) and the interfering wife of Alan Alda's character in Whispers in the Dark (1992). After appearing in Ben Gazzara's Beyond the Ocean (1990), which was shot in Bali, and the unreleased Pretty Hattie's Baby (1991), she became typecast as an attractive maternal figure: she was the long-missing matriarch in Rich in Love (1992), a wheelchair-bound mom in Firestorm: 72 Hours in Oakland (1993) and Eric Stoltz's single mother in Naked in New York (1993). A review in People magazine felt Clayburgh "[did] her best as the footloose mother" in Rich in Love, while Roger Ebert praised her casting in Naked in New York as "exactly on target". She also played Kitty Menendez who was murdered by her sons in Honor Thy Father and Mother: The True Story of the Menendez Murders (1993), a role which Variety perceived to be "incomplete, but that has more to do with the script than Clayburgh’s performance." She continued to play concerned, protective mothers in For the Love of Nancy (1994), The Face on the Milk Carton (1995), Going All the Way (1997), Fools Rush In (1997), When Innocence Is Lost (1997) and Sins of the Mind (1997), and was in "good form" as the forceful, pushy stage mother in Crowned and Dangerous (1997).
