in the movie crimson tide how does denzel Washington deal with stress
No, but Laurence Fishborne did.
He costarred with a chimp (not a monkey) in Bedtime for Bonzo, 1951. See the link below.
They only costarred in one movie : TOWERING INFERNO (1974). Steve McQueen had a very small part in SOMEBODY UP THERE LIKES ME (1956) in which Paul Newman starred, therefore we can't say they were costars in that movie.
