Liam Neeson and ‘Taken 2” are looking at a $48 million weekend after blasting past their box office rivals Friday and rolling to a first-day total of $18.6 million. The gangbusters debut for Fox’s PG13-rated action sequel marks the second consecutive week a movie has broken out and lifted the box office into positive territory. If the weekend stays on pace, it will finish more than 30 percent ahead of last year, when “Real Steel” lead the way with a $27 million debut.
