When a Texas cotton farmer’s land stops yielding crops, he teams up with an old friend to distribute VHS pornography tapes; leaving his family and slipping into a world of depravity and greed to become the undisputed King of Pornography in Texas. (1980)

Agree with the others. As well, clarify if it's production and not just distribution because it's hard to see depravity with the latter. With depravity, greed becomes secondary or an assumed part of it.

Even if this is based on someone real, try to strengthen the hook and family part so that this can be more than 'Boogie Nights in Texas'.

Does his goal become getting back with his family?

Is this based upon? by a real life character?
