[This post contains POSSIBLE SPOILERS for Spider-Man: Homecoming]

Next summer's Spider-Man: Homecoming is making its way through principal photography, and fans everywhere are anxious to learn more about the project. San Diego Comic-Con featured a variety of updates about the film, such as director Jon Watts revealing supporting character names and a sizzle reel confirming that the Vulture will be the primary antagonist. At the same time, there's still a great deal of mystery surrounding the movie, as several actors (like Donald Glover) are in undisclosed roles. Even the characters who have been named may not be what they seem. It was recently reported that Zendaya's "Michelle" is actually Peter Parker's longtime love interest Mary Jane Watson.

Studios always work hard to keep their deepest secrets under lock and key during production, but leaks invariably do happen from time to time. It would appear that Homecoming was just hit with a big one, as an apparent call sheet has made its way online, hinting at more characters viewers will see in the film.

An image of the sheet was first posted on Twitter by Atlanta Filming (and has since been deleted), but the picture has made its way across the Marvel Studios Reddit thread. Going by the information presented, it is for a scene that is set in Midtown High School. Tom Holland is listed among the talent, as are his classmate co-stars Jacob Batalon, Tony Revolori, Zendaya, and Laura Harrier. In addition, a number of actors seem to be playing members of the Midtown faculty and staff, such as Kenneth Choi's Principal Morita. It's important to note that "Z" (Zendaya) is referred to as Michelle and not Mary Jane, but that could be a ruse.

The biggest takeaway from this call sheet will be the inclusion of Bokeem Woodbine, who is said to be playing Herman Schultz, a.k.a. The Shocker. During Comic-Con, a toy panel suggested that the Vulture wouldn't be the only villain featured in the film, and the later casting of Michael Chernus as the Tinkerer served to confirm that. When Woodbine first joined Homecoming back in June, it was stated he would be playing a bad guy, so the call sheet lines up with what we've heard. The notion of having three recognizable Spider-Man villains in Homecoming brings back unfavorable memories of the bloated Spider-Man 3 and The Amazing Spider-Man 2, but it's worth withholding judgment until the final product makes its way to the screen.

Another interesting tidbit on the call sheet is actress Angourie Rice (The Nice Guys), who is listed as Betty Brandt. Readers of the comics and fans of the Sam Raimi Spider-Man trilogy will remember Brandt as J. Jonah Jameson's secretary at the Daily Bugle. At 15 years old, Rice would be a bit young for that position in Homecoming, so Watts seems to be doing something a little different with the source material. Of note, Batalon is confirmed to be portraying Ned Leeds, who in the comics went on to marry Betty. Considering the call sheet is true, how all these pieces come together will be fascinating. Homecoming clearly is not following the comics verbatim, and many will be curious to see the results.

Now that this information is making the rounds, all eyes will be on Marvel Studios to see what their course of action is. The company has a humorous history of dealing with leaks in the past (their famous "Dammit, Hydra" tweet after the Age of Ultron trailer), but they may not be ready to make any comments regarding this just yet. In the meantime, viewers have plenty to theorize about as they wait for an official trailer.
