There's a number of cute cameos, like Bob Newhart as the Principal, and Tom Selleck as an Inside Entertainment reporter trying to milk a story out of it.
Ok, so I'm unsure if I missed a scene or if it was cut for time, but why -was- he marrying the lovely Ms.Cusack? Was she a "beard", as the slang term goes, like some rumors about Cole Porter's wedding? Did he not come to terms with himself until after dating her, and continued it out of a sense of obligation? Did he not come to terms with it until the wedding itself? It seems a bit big of a point to just leave it untouched on.
Woo hoo! 4400 on after it! At this rate, I probably shan't watch Torchwood until this weekend.
