                <p>LOS ANGELES (Reuters) – Thriller "Limitless" topped box movie office charts in North America with $19 million in ticket sales over another lackluster weekend for Hollywood, according to studio estimates on Sunday.</p>
                <p>
The movie, in which Bradley Cooper portrays a man who is able to exponentially increase his brainpower by taking a drug, beat animated family film "Rango," which maintained the No. 2 spot in its third weekend in theaters with $15.3 million for a slight 32 percent drop from a week ago.</p>
                <p>
Rounding out the top three was last week's No. 1 movie, alien invasion flick "Battle: Los Angeles," which saw its box office slide nearly 60 percent from last weekend to $14.6 million.</p>
                <p>
"Limitless" was released by closely held Relativity Media, "Rango" by Paramount Pictures, a unit of Viacom Inc and "Battle: Los Angeles" by Columbia Pictures, a part of the media division of giant Sony Corp.</p>
