If we're talking adjusted numbers I gotta say Forrest Gump deserves to be discussed. It's a human dramedy with a focus on culturally significant events but still take a step back and think about the fact that is adjusts to over $650 million today. What's more it came literally just weeks after TLK which also adjusts to over $600 million.
1994 was crazy. I mean, I don't think we've had two films selling more than 70 million tickets in the same year since.
