This movie cost $150 billion dollars to make

Someone in Hollywood has hefty pockets. Imagine the conversation that goes by to make a movie for a cool $300 million.

Quentin "Hey Harvey I got a movie idea."
Harvey, smoking a pipe and watching television. "What is it and what is going to cost?"
Quentin "Its a sci-fi in the same era of the 70's slasher movies, but this time Uma will play the male dominated role of Wackerbee."
Harvey is interested, he sets his pipe down. "I like it so far. How much?"
Quentin "Well, I won't bullspit you. I'm going to need $400 million and I want distribution percentages."
Harvey coughs up a lung. "I'll give you $300 million, but I won't give you distribution, but you can direct it."

If only that kind of dreams would be that easy to pursue. The reality is that movie budgets ARE EXAGGERATED TO EXTREME HEIGHTS.

Here are some figures to look at. Note that the numbers are not based on inflation.

Pirates of the Caribbean: At World's End $300 million
Spider-Man 3 $258 million
Harry Potter and the Half-Blood Prince $250 million
Pirates of the Caribbean: Dead Man's Chest $225 million
The Chronicles of Narnia: Prince Caspian $225 million
X-Men: The Last Stand $210 million
Superman Returns $209 million
King Kong $207 million
Quantum of Solace $200 million
Spider-Man 2 $200 million
Terminator 3: Rise of the Machines $200 million
Terminator Salvation $200 million
Titanic $200 million
Transformers: Revenge of the Fallen $200 million
The Dark Knight $185 million
Wall-E $180 million
Waterworld $175 million
G.I. Joe: The Rise of Cobra $170 million
X-Men Origins: Wolverine $150 million
Star Trek $150 million

Transformers $150 million

Notice anything yet(besides bad html)? Almost all these movies were made within the last decade.
Before the 90's boom of blockbuster moviemaking, budgets were already getting ridiculously high, but the exaggeration of the amount it took to make them was noticeably more minimal. If there could be a few movies that started this game of who spends more money, it would probably be Terminator 2, Jurassic Park, and Mission Impossible.

The general public seems to go wide eyed when an astronomical figure is thrown at them with how much a film took to make. The importance is that nobody actually cares if a movie cost the entire world to make or if it was made for $23,000 in the woods of Pennsylvania.

Gee, maybe movies need bigger budgets to be better you might be saying.

By the way...highest grossing movie so far? Yup, you guessed it.
Titanic with $1.9 billion in revenue.
