How much is a function of budget? Dune II cost $190 million which would put it maybe around ~100 in terms of most expensive films ever made. Looking at the others (https://en.wikipedia.org/wiki/List_of_most_expensive_films#Most_expensive_films_(adjusted_for_inflation)), they all seem pretty safe. Maybe Indiana Jones was a little risky.
