Wednesday, 7.30pm, SoHo This just in, as they say on TV. The new season of Smash debuts tonight on SoHo on the very same day it goes to air in the US. Needless to say I haven’t seen it, but word is Sean Hayes, who used to work with Smash lead Debra Messing in Will & Grace, joins the cast of the big-budget drama. It will be interesting to see if his character is as different from Jack McFarland as Messing’s is from the daffy Grace Adler. Smash, about the making of Bombshell — a musical on the life of Marilyn Monroe — also welcomes the supremely talented Jennifer Hudson this season. The plot arc is that some of the cast of Bombshell are attracted to a rival musical, like Grizabella to a street lamp.
