One problem with threads like these is, a lot of the time, people post pictures of celebrities when they weren't over 40. If I listed Michelle Pfeiffer as a hot actress over 40, and then posted a picture of her as Catwoman, that wouldn't make much sense.
I think some recent pictures (from 2011) are here:
"Green Cross International has appointed international actress Famke Janssen as its first “Water Ambassador,” a role aimed at helping the global organization increase awareness on the global water crisis and their efforts to respond to this challenge." http://www.imdb.com/news/ni24419104/ http://www.gcint.org/
