Sure. They're character actors, not leading men. You can also see how those kind of movies usually have A-list character actors, but B-list* leading men - Emmerich's leads in his disaster movies were guys like Matthew Broderick, Dennis Quaid, John Cusack. Hell, for Independence Day 2 they decided they didn't need Will Smith and went with Liam Hemsworth instead.
This kind of movie, you need good actors to make them work, but you don't need big names to draw people in. The disaster // giant monsters/robots will do that for you. Stuff like Spielberg getting Tom Cruise for War of the Worlds is quite unusual really.
*By that, I am not commenting on their abilities as actors, just on how much it'll cost to employ them.
