Sony is developing movies based on lesser-known Marvel characters Silk, Jackpot, and Nightwatch, and was looking for writers last summer, according to Variety.
Introduced in 2014, Korean-American superhero Silk is relatively new to Marvel Comics. She has a similar origin story and powers as Spider-Man, and also gained her abilities through a radioactive spider bite.
Jackpot first appeared in 2007. The first version of the character was a government-registered superhero as part of the "Initiative" program following Marvel Comics' "Civil War" mini-series.
Nighthawk first appeared in 1993, but his origin has been retold throughout his comics history. When first introduced, Kevin Trench finds a dead version of himself from the future, and takes up the costumed identity of his future self.
