Hackman played the same character in both movies. His character in enemy of the state has some deliberate references (the raincoat, the workshop, the opening sequence).

Oh? Thanks for the recommendation, I'm a big fan of Hackman's acting and spy movies especially-lately, so I'll definitely be looking this up. Cheers

Francis Ford Coppola said that “The Conversation” was his favourite Francis Ford Coppola movie.

Watching “Enemy of the State,” it is quite clear that Hackman’s character is a nod at The Conversation’s Harry Caul. He plays an ex-spook who is extremely paranoid about surveillance, which is the exact state Caul gets into at the end of The Conversation!

Directed by Francis Ford Coppola
