To be honest, I enjoy all different types of films and experiences.

My go-to prebikini flat-ab move is the plank, all different types.

Different times need different types of leadership.

Playing different characters in different films helps keep you excited about what you do. It always seems like a whole new adventure.

I get to partner up with all different types of opportunities.

We do need different types of propulsion to get to Mars. I wrote one of the first Ph.D. theses on that in the 1960s.
