era só para dizer que há um filme em que ambos aparecem e em que se parodia a personagem do martin sheen no apocalypse now. Pai e filho cruzam-se por instantes nesse filme - Hot Shots! Part Deux (1993). Encontrei isto na net:
Scene: Charlie Sheen is on a PT boat recounting the horrors of war. He looks up as another voice drowns his dialogue out. Standing up he sees his dad Martin Sheen (reprising his Apocalypse Now role of Capt. Benjamin L. Willard) approaching. Simultaneously they state, “I loved you in Wall Street” as their boats pass each other in the river. It’s classic because it commemorates the fact that they both starred in Oliver Stone’s ode to greed and having the star of one the most vivid war movies make fun of the genre is cool too.
