The easiest way could be to search for it on your favorite video-on-demand service. But make sure you have a valid subscription. You might also find it on some free streaming sites, but the quality and legality could be questionable.
Well, sometimes it's available on cable TV channels that focus on movies or dramas. Or you could check out some specialized online movie websites, but make sure they're legal and reliable.
I think Amazon Prime Video or Disney+ might have it. But sometimes, availability depends on your region. You could also search on Google and see which platforms come up with the option to watch it.
You could try looking on Hulu. Also, some local video rental stores might have it in their collection. Another possibility is to search for it on digital movie stores like iTunes or Google Play Movies.
