The list below was taken from an official casting sheet (via Twitter's @Marvel_Spider) of Czech actors being drafted in to work on The Amazing Spider-Man 2, and as you can see, it seemingly confirms that the mysterious character being played by Felicity Jones is indeed none other than Felicia Hardy, a.k.a. Black Cat. The last time we heard anything about this character was Anne Hathaway being in the running to play the character back when Spider-Man 4 was in the works.
Who wants to bet that she's only working at Oscorp to steal something? Either way, fans have suggested from the very start that she'd be a perfect choice for the role, and it seems likely we may see her don the tights and mask in 2016's The Amazing Spider-Man 3!
Matouš Ruml – Spiderman, Peter
Kateřina Peřinová – Gwen (dříve Velebová)
Max, Elektro – Lukáš Hlavica
Goblin, Harry – Petr Neskusil
Rhino, Aleksei – Bohdan Tůma
teta May – Martina Hudečková
Helen – Regina Řandová
Kafka – Tomáš Juřička
Mary – Lucie Svobodová
Menken – Václav Knop
Norman – Miloš Vávra
Richard – Jakub Saic
Stacy – Jiří Schwarz
Philip – Daniel Krejčík
Kari – René Slováčková
Smythe – Pavel Tesař
Felicia – Jana Páleníčková
Now, while Jones' name is never mentioned in the list above (none of the English speaking actors are), we can see all the characters with significant speaking parts listed there. The fact that "Felicia" is one of them, seems to make it a pretty safe bet that that is indeed who she's playing and that the character IS in the sequel. What do you guys think?
