“The Taking of Pelham 123” is shaping up as a relative disappointment while Eddie Murphy has another dead-on-arrival flop, based on early Friday numbers. Steve Mason is predicting Tony Scott‘s remake with Denzel Washington will finish the weekend with $26 million, behind “The Hangover” and “Up.” Mase foresees an even more dire fate for Murphy’s “Imagine That” — $6 million over three days, or slightly more than Murphy’s last disaster, “Meet Dave,” which cost twice as much as “Imagine That.”
