Seems to me that the Ray Donovan character is somewhat based on former P.I. to the stars Anthony Pellicano who i believe is still in prison. Ray takes care of all the problems of the rich and famous and will do whatever it takes to get them off the hook, just like Pellicano used to.

Mickey is the best, he keeps the show interesting IMHO.

BTW, the shows executive producer Bryan Zuriff just pleaded guilty to running a gambling operation tied to the Russian Mafia. The article said he faces up to 5 years.
