Probably good to define the period known as the Renaissance which is generally discussed as encompassing the 15th into the 17th century. That's c. 1400 up to maybe 1650.
This means the story of Excalibur took place not quite 1,000 years before the Renaissance period and that of Barry Lyndon a century or so after the Renaissance ended.
The Agony and the Ecstacy indeed the story of Michaelangelo a leading renaissance artist.
"Elizabeth" is a good relatively recent look at this period and Elizabeth I. If you can find it "A Man for All Seasons" about Thomas More.
Shakespeare did his writing in the latter part of this era - surprising so many of his plays have been moved into different time periods, so it is hard to get a Renaissance look or feel from modern versions, but there is plenty of Shakepeare available.
