Lucy: The Dumbest Movie Ever Made About Brain Capacity. An extended spoilereview of Luc Besson's worst film to date. As the brain capacity of Scarlett Johansson's character Lucy rises, all semblance of logic plummets.
Place in a preheated 180Â°C oven and cook for 40 minutes per kilogram. Rest under foil for 5-10 minutes. To aid even cooking, place roast on an elevated rack in the oven or onto halved carrots or potatoes to elevate.
Set the oven timer so the roast cooks for 20 minutes per pound. Since the oven defaults to HI -- the correct temperature for cooking a chuck roast -- you do not have to adjust the temperature.
