EXCLUSIVE: KTLA Los Angeles entertainment guru Sam Rubin has been tapped to host the 18th annual Critics’ Choice Movie Awards, which will air live tomorrow from 8-10 PM PT on the CW. The confirmed guest list includes just about every actor or actress who has been in season-long discussions for the Oscar nominations, which will have been revealed earlier in the morning. That 5:38 AM wake-up call always makes for a long day for the entertainment journos in town, but it will be especially daunting for Rubin, who will cover the noms announcement at 5:38 AM, do his regular shift on the KTLA Morning News and then host the station’s two-hour Critics’ Choice red carpet show before jumping onstage to host the ceremony. Scheduled presenters include Nina Dobrev, Joseph Gordon-Levitt, Melissa Leo, Eva Longoria, Cory Monteith, Rob Riggle, Emmy Rossum, Ian Somerhalder, Octavia Spencer and Paul Wesley.
