Hollywood star Robert Downey Jr. was left speechless after meeting his idol, legendary director Steven Spielberg. The actor was in between takes for his forthcoming movie The Soloist, where he plays an inquisitive journalist, when the Jurassic Park filmmaker dropped by for a chat.

However, despite waiting 25 years to meet his hero Downey Jr. couldn't manage more than a few words.

He says, "I couldn't believe it. He's over by the monitors and I'm like 'Jesus Christ, there he is' and he talks to me about a couple of things and then he leaves the set and I'm like 'God darn it! I've only been waiting 25 years to have one of those moments.'"
