I havn't seen pi, but pi and Phi are completely unreleated. This number has nothing to do with hollywood. There are a tun of reputable sources researching Phi.
Read the following webpage

Saying that people are finding Phi everywhere (in math, biology, astronomy, ect) is a result of obsession with the number is silly. First off defined irrational numbers are very rare. Then we have a sequence which converges to that number. Then we find that number in nature. Look at how many different ways Phi is defined on that mathworld page my favorites is the nested radical and continued fraction.
