River Phoenix played Harrison Ford's eldest son in Mosquito Coast (1986), and portrayed a young Indiana Jones in Indiana Jones and the Last Crusade (1989). The two actors display definite chemistry on film, but I never thought they resembled one another. Then the other night I watched Running on Empty (1988) and BOOM, I could see it. In an opening scene a brunette Phoenix tinkered on his bike as feds cased his house. As the wind blew his hair, he looked just like Ford in Mosquito Coast.
