Slattery has this perfect look of looking like Howard. He looks like a 56 year old Tony. Not necessarily a bad thing.

Slattery is better, but both are God-tier castings.

They were both great for the different age rules they were playing, in my opinion.

Dominic

I agree with the above comments. they were both superior castings for each age of howard

Dominic Copper was a better Howard Stark

I pay more attention to a character's actions than to who plays the character. this is not an exception.

younger Howard seemed to care more about others than older Howard.
