10 Cameos That Must Happen In 2015's Biggest Movies

7. Robert Patrick Terminator Genisys

Terminator Genisys - in spite of the somewhat silly name - is a hotly anticipated movie. With an impressive cast that includes the likes of a returning Arnold Schwarzenegger as the T-800, Jai Courtney, J.K. Simmons and Matt Smith, it will undoubtedly be one of the highest-grossing movies of the summer. What with Arnie making another triumphant return to the franchise, wouldn't it be cool to see Robert Patrick - who famously played the T-1000 in Terminator 2: Judgement Day - making a return of his own? He could perhaps play the man who designed and/or created the T-1000 and, as a result of that, whose likeness was used for its appearance. Subtle and fun.
