Evolution of film budget

Im interested in looking at how the budget of films evolve over there success, starting with a recent film like one of the many batman franchises.
Batman (1966) budget $1,400,000 box office: Unknown
Batman (1989) budget $48,000,000 Box office: ~$411,348,924
Batman returns (1992) budget $80,000,000 Box office ~$282,800,000
Batman forever (1995) budget $100,000,000 Box office $336,531,112
Batman and robin (1997) budget $125,000,000 Box office $130,000,000
Batman begins (2005) budget $150,000,000 Box office $372,710,015
The dark knight (2008) budget $185,000,000 Box office $1,001,921825
The dark knight rises (2012) Budget $250,000,000 Box office $1,013,114,000 

Through this i can see that the batman is relay running on its franchise making huge profits, even when the film seems to not profit alot.
