As if he wasn’t busy enough with ’30 Rock,’ guest spots on ‘SNL’ and his new autibiography, Alec Baldwin is co-hosting “Essential” on Turner Classic Movies. It’s the must-list of classic movies going into its ninth year. Baldwin starts that up in March so we can decide then about taking his advice on the best cinema we may have missed. Oh, and he’ll be hosting as Malcolm, his character from ‘Will & Grace.’
