I have to wonder if this idea was polled or put before a focus group because it sure seems like a yawner to me.
Here is a link to
an article (with cast picture) about it.
And, yeah, Larry Hagman, Patrick Duffy and Linda Gray are in it. Not that it will matter all that much since undoubtedly most of the scenes will necessarily revolve around the new and younger cast members. Viagra or not, it's pretty difficult to get any excitement built up around the 79 year old Hagman or the 69 year old Duffy let alone 78 year old Linda Gray. It appears that Victoria Principal has had the good taste to stay away from this likely train wreck.
Who knows, though? Maybe there is a demand for hot septuagenarian and/or octogenarian sex drama.
Still, some things are better left to reruns and memories and this sure sounds like it should have remained in that category rather than resurrected from the dead. Just because you can do something doesn't mean you should do something.
