Comic-Con wrapped up the weekend's festivities Sunday with several exclusive trailers and panel discussions highlighting upcoming seasons of popular television shows.
The BBC's "Sherlock," which airs in the United States on PBS, will debut its latest season next year, and Sunday's panel about the show featured lead actor Benedict Cumberbatch, who plays the legendary super-sleuth; co-star Amanda Abbington; and co-creators Mark Gattis and Steven Moffat. Many of those in attendance described the season trailer as "intense."
Also Sunday, creators of "Supernatural" announced that veteran rock singer and actor Rick Springfield will play Lucifer on the CW show, now entering its 12th season.
That wasn't the only surprise: During a question-and-answer session, a man asked his girlfriend to marry him.
Other major announcements included reboots of Fox network hits "24" and "Prison Break," the latter of which featured a two-minute sneak peek.
Another panel during Comic-Con's last day focused on women who work for Marvel Comics. The participants discussed what it means to succeed in a male-dominated industry.
The last day of the hugely popular festival is considered somewhat low-key compared to the first three days, which featured an announcement that Oscar winner Brie Larson will play Captain Marvel in an upcoming movie.
