Actor Paul who played a little role getting the red-eye (4)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

This looks like a double definition, though there may be more to it. There’s a US actor called Paul Rudd, who has appeared in a lot of films and TV shows, but I don’t think I’d recognise him from anything I’ve seen; and there’s a fish (genus Scardinius ) that can be called a rudd or red-eye. I don’t know what the words in the middle are intended to add, unless they’re pointing to a particular role that Rudd played? UPDATE: Matthew Newell (comment 3) points out that Paul Rudd played the “little” title character in the film Ant-Man . I thought it might be something like that.
