You need more original title. There has been a film called Africa, there’s been even a song called Africa.
I like your slug line and I would love to see a film about a man and a lion!
I like the flow of the script. No complicated sentences, it reads easily.
Some action lines could be changed so that you show rather than tell. For example ‘Wade's words make James angry.’ It could be ‘Wade’s eyebrows narrow, his face reddens…’
I would omit the action line ‘Wade yells angrily.’ I would put it as parenthetical,
I hope you know what I mean. No need to point out that he’s yelling angrily as people don’t yell calmly.
I like the script, may come back and read it all.
