Was skeptic Susan Blackmore the inspiration for Sigourney Weaver's skeptical role in the movie Red Lights?

In a previous post, I commented about the movie Red Lights, which (I argued) was apparently promoting pseudo-skepticism in Hollywood. I was only partially wrong, but I won't tell you the story of the movie, you should watch it by yourself (it is a very good movie, by the way... you are going to enjoy it a lot).

I'm going to comment only that one of my top favorite actresses, Sigourney Weaver, features a nice but tough-minded, highly intelligent woman and very experienced and trained experimental scientist, whose professional experience dealing with "psychics" has made her a hard-nosed skeptic. She fully knows the fake psychic's bag of tricks and how to design experiments to expose them.

I suspect that Weaver's role was inspired in professional skeptic Susan Blackmore. Although less eccentric than Blackmore, Weaver's role is very similar in her scientific approach and moderate manners (not a Randi-like type of rhetorical skeptic), specially regarding the fact that her skepticism is based on her own personal scientific experience. 

In fact, when a student questions her about whether she thinks that all paranormal claims are false, she answers that she's not saying such a thing, that her point is that most of them can be explained in conventional ways, according to her experience.

Remember that Blackmore has said that she didn't find any convincing scientific evidence for psi (this is not exactly like that, because she has admitted in Confessions of a Parapsychologists that "The other major challenge to the skeptic's position is, of course, the fact that opposing evidence exists in the parapsychological literature. I couldn't dismiss it all." (p. 74), so actually she knew that positive scientific evidence did exist for psi, only that she couldn't find it in her own experiments).

The end of the movie is, for a large extension, very unexpected. I think this movie should be watched by all fans, students and reserachers of parapsychology and psychic research, and even pseudoskeptics will surely like it, except for...

PS
I ask all the readers that, while watching the movie, ask themselves: Am I more sympathetic to DeNiro (the psychic) or to the researchers (Weaver and Cillian)? This test will tell you a lot about your own prejudices...
