Beverly Hills COBRA?

Anyone else familiar with this story? Allegedly Sylvester Stallone was set to write and star in Beverly Hills Cop. His screenplay ended up being so Over The Top that the studio didn't have the Tango & Cash to make it happen. Result? It became COBRA. We are planning a double-feature soon and will keep a copious log of the parallelisms. Sorry to leave you on such a Cliffhanger!
