James Gunn's tweet for charity is approaching its lofty goal.
It began with a tweet at Gunn about releasing the Zack Snyder's Justice League cut.
The Guardians of the Galaxy director pledged to donate $1 to Rainforest Trust for each retweet, up to 20,000.
His followers and others have retweeted the tweet close to 18,000 times.
Some fans have wondered why Gunn didn't simply make a $20,000 donation.
Gunn seems to be using the tweet to raise both money and awareness for Rainforest Trust.
