If you gave any one of our big tech industries millions of dollars, a team of computer geniuses and cutting edge technology, they would probably waste it on AIDS vaccine research or nanocomputers or something. Hollywood will invest it in CG penis enhancement.
The reason is sometimes hours of makeup and the perfect lighting still aren't enough to make some stars look like stars. Welcome to the world of "vanity visual effects."
7Angelina Jolie's Naked Body in Beowulf (2007)
Beowulf continued the proud tradition of "performance capture" earlier exhibited in Polar Express, where real actors' bodies and motions are painstakingly captured and digitized into the computer world to play terrifying dead-eyed zombies (it is believed eye performances were captured separately, from that cupcake dog.)
In Beowulf, Angelina Jolie plays a nude lizard woman. In an interview, Jolie speaks about how shy she was about having her naked body scanned for the part, which is odd considering that the body you saw in the film came from Rachel Bernstein, who "has made a living winning swimsuit competitions" while "appearing in almost every lingerie catalog in LA."
That resume certainly qualifies her for the role, but leaves a few questions unanswered. Angelina Jolie, by all appearances, has a perfectly fine body, and any worrisome changes due to her three-month pregnancy at the time could have easily been touched up as they freely admitted to doing with the male actors.
"Ugh, she is hideous. Hire a body double, I'm gonna puke."
It might just be a symptom of society's double standards that actors can freely brag about getting better fake bodies while actresses have to keep up a pretense of being physically perfect. Or maybe she honestly didn't know. It certainly seems possible that when Angelina Jolie asked if they needed her to disrobe to have every square inch of her naked boobs scanned into a computer, some unscrupulous devil at the Sony scanning lab conveniently forgot to mention the body double.
6Kevin Costner's Hairline (and Neck Vaginas) in Waterworld (1995)
Waterworld holds a special place in entertainment history as one of the easiest punchlines of all time. When produced in 1995, for a budget of $175 million, it was the most expensive film ever made; money clearly well-spent on CG representations of things you can't find in real life, like the ocean. It turned out that, in addition to the planned out effects, after shooting had wrapped, some unfortunate observations came to light, such as the fact that Kevin Costner was losing his hair.

At this point, Costner realized that audiences would never be able to take his role as a half-fish/half-man seriously if they kept being distracted by his male-pattern baldness. Costner reportedly asked for reshoots and CG fixes, leading to one of many arguments that eventually got director Kevin Reynolds kicked off the movie.
Costner may have been inspired by another aging action hero. In 1991, it was rumored that Bruce Willis ordered his thinning hair touched up in Hudson Hawk which, if true, would have been even more ridiculous, budget-wise, as photorealistic CG wasn't available in 1991, and the hair would have had to be pretty much hand-painted frame-by-frame by a 2D artist. It seems like Costner may have taken the wrong lesson away from this cautionary tale of vanity (The biggest flop of the 90s prior to Waterworld? Hudson Hawk).
More understandable was some after-the-fact CG gill modification. Costner, as a fish-man in the movie, had gills on his neck. Above water they looked like gills, while underwater, as it turns out, they looked like vaginas. Needless to say, additional budget was found for some quick digital fixes. While they had saved themselves from losing the "family" audience, sales in Japan would suffer.
