The problem is, however, that there are no indications "he" (Routh) has the "ability" or that he can deliver an outstanding performance as Clark/Kal. Cause that is what it will take.
When Routh was cast many pointed to his OLTL run and how he was fired from that soap because of consistently poor performances. His delivery among them - and you can see that very weakness in Routh's lines with Martha (EMS) early in the film. Or his poor timing in his bar scenes with Jimmy/Sam. The two actors were not connecting and it was not Huntington who was the problem.
Remember, in the years between his OLTL firing and being cast in SR, Routh did very little work. No opportunity to grow his skills. Why would anyone have expected him to suddenly flower as an actor when cast as Clark/Kal? Singer may have been known for picking a great unknown talent in Jackman but his rep in that regards takes a blow with the casting of Routh.
If Routh "jacked" his performance early on and Singer then adjusted by giving Routh hardly any dialog in SR then what does that say about Singer's casting skills or judgement? An actor either has the skills to pull off such a complex role or not. WB had to have seen this, so I assume Singer and Routh came as a package and, if WB had insisted on a different actor, then Singer, their "white knight", would have walked.
As to any sequel, why would anyone expect to see an improvement in Routh's performance when he has done nothing acting-wise since SR came out?
I know there are Routh supporters out there and he may be a very nice guy, but he has neither the skills nor is he showing the passion to "want it" - as in being out there and pursuing work IMO. Sorry, he can't afford to be turning down roles which he reportedly is. Its why I question his passion for this craft - if you don't have that then you can forget it.
BB, the Spiderman films and the X-Men films were not training grounds for novice actors with just average skills - why Superman should be I simply dont get. But I guess I am just funny that way.
