Somebody, I won't say who, is on a Tom-Hardy-lesser-known film jag at my house. First two offerings:
Dot the I (2003) - Bizarre love triangle with not one major twist, but two. Hardy has a small role as a young flunky for the perpetrator. On Prime.
Locke (2013) - All the action takes place with Hardy's character, a married family man who has an ultra important international contract, who throws it all away as he drives to London to be with the woman giving birth to his child. Lots more interesting than the summary sounds. Available on several platforms. I watched it on Tubi.
Next up, Lawless (2012) on Pluto.
