I'm sure you heard at least one such and many times over at that:  "Adagio"
billed as Albinoni's, not to mention the infamous "Diamond music" /
"Palladio" which fooled many people into thinking it was genuine Baroque.
Are you sure you would love to hear it again?

A few years ago, three movies directed by Kieslowski were very popular
("Red", "White", and "Blue"), and they featured music by Zbigniew Preisner
- in Baroque style, hiding behind the fictitious name "Van Budenmeyer".
People liked it.

Plenty of movie music has been written in the style of previous epochs.
