Lawrence Fishburne was in "Class Action" with Gene Hackman
Gene Hackman was in "A Bridge Too Far" with Laurence Olivier.
From your past questions................
Elvis Presley was in "Clambake" with Teri Garr,
Teri Garr was in "The Player" with Nick Nolte
Chris Pine was in "Smokin' Aces" with Patrick St. Esprit
Patrick St. Esprit was in "We Were Soldiers" with Chris Klein
President McKinley was in a documentary that was about the inauguration that also included Theodore Roosevelt.
Teddy Roosevelt was in "Womanhood, the Glory of the Nation" with Walter McGrail. (President Woodrow Wilson was also in this movie (not a documentary) )
Now Walter McGrail stared with Henry Fonda in "The Grapes of Wrath"
Henry Fonda was in "Breakdowns of 1938" with Ronald Reagan.
Now if you want a really hard one:
Connect Ronald Reagan to John Wayne. Seems Easy with both of them making movies at the same time, living in about the same place (SoCal) and both doing westerns. But that one is a real bitch.
Otherwise,
Jimmy Smits and Jimmy (James) Stewart
