Hawkeye

It is highly recommended to watch Avengers: Endgame before viewing the Hawkeye series, as the show deals heavily with Clint Barton's trauma from the Blip and his time as the vigilante Ronin. The events of the Black Widow movie are also briefly referenced regarding his past. However, the series stands relatively well on its own as a street-level, holiday-themed adventure.

The character of Kate Bishop, a young archer and Clint Barton's biggest fan, is played by actress Hailee Steinfeld. Steinfeld is well known for her roles in True Grit and the animated Spider-Verse movies. Her dynamic with Jeremy Renner's Clint Barton is the central emotional core of the Disney+ series.

Yes, Wilson Fisk, also known as the Kingpin, makes a major appearance in the finale of the Hawkeye series. He is portrayed once again by Vincent D'Onofrio, reprising his iconic role from the Netflix Daredevil series. His presence officially brings the Daredevil universe into the mainline Marvel Cinematic Universe continuity.

In the series, the Avengers tower Rolex watch is revealed to belong to Laura Barton, Clint's wife, and contains a transmitter revealing her location. The watch signals that Laura was a former S.H.I.E.L.D. agent, explaining how she and Clint originally met. Clint retrieving the watch from the Tracksuit Mafia is what finally allows him to return home for Christmas.
