Legal Eagles starring Robert Redford, Debra Winger and Daryl Hannah.

And of course, although it’s not “only” a legal film,
Kramer vs. Kramer is a 1979 American legal drama film written and directed by Robert Benton, based on Avery Corman’s novel. The film stars Dustin Hoffman, Meryl Streep, Jane Alexander and Justin Henry. It tells the story of a couple’s divorce, its impact on their young son, and the subsequent evolution of their relationship and views on parenting.
To stay in the k-drama realm, I enjoyed Suspicious Partner and most of all Room n. 9 with three excellent main actors.
Terrific acting by the wonderful Lee Sung Min and a compelling story in Memory. Make sure you’ll watch this one, you’ll be glad you did.
You can find a virtuous prosecutor against an immoral lawyer in While You Were Sleeping, but the drama is lukewarm: nice and pleasant to watch but nothing to write home about.
I heard good things about Defendant but I haven’t watched it.
