"Even though these days I'm very selective about what roles I want to do, I will do Stargate anytime they call"

Ronny Cox's quote recommends that he is really specific about the roles he selects to handle, but he wants to make an exception for the Stargate franchise. This could be since he has a special connection to the franchise, or since he believes in the quality of the work. It might likewise be because he has a strong fan base that would be thrilled to see him in a Stargate movie. Whatever the factor, it is clear that he is willing to make an exception for the franchise and is open to returning to the series if they call. This reveals his dedication to the franchise and his appreciation for the fans who have actually supported him throughout his career.
