I want to know the answer to the following question:
If if a cinematographic film were taken by means of physical  laws and then played backwards, it would still portray what?
All the background I'm provided with is that "Firstly, the fundamental physical laws are time-reversal invariant; if a cinematographic film were taken of any process describable by means of the aforementioned laws and then played backwards, it would still portray a physically possible process.". Is that enough to answer the question?
Answer: yes
