Yes, but TFA also had about 16 years of inflation to help inflate its budget vs. TPM. And as it was the first $2.0B grossing film since Avatar, I'm guessing Disney sees it as money well spent, regardless of how some of us view it now..I don't know, other than Ford, who was the "big name" of the time in that movie?
Carrie and Mark were doing nothing, more or less. Driver and Gleeson were marginal names at best at the time - good actors but not marquee names. And Sydow worked one day.
Who else was in this?
Seems like TPM had bigger names -- Neeson, McGregor, and SLJ... even Portman (not a big name but I was well aware of her at the time)
