Benedict Cumberbatch is set to appear at the San Diego Comic-Con for the very first time.
The Sherlock actor will be on the DreamWorks Animation panel to promote his new feature Penguins of Madagascar along with co-stars John Malkovich and Tom McGrath.
The 90-minute presentation is to take place on 24 July in the convention centre's Hall H and will also feature directors Simon J. Smith and Eric Darnell.
Released on 26 November, the Madagascar spin-off follows penguins Skipper (McGrath), Rico (John DiMaggio), Kowalski (Jeff Bennett) and Private (James Patrick Stuart) and a wolf named Agent Classified - a suave secret agent portrayed by Cumberbatch.
BBC1 series Sherlock has hosted a panel at Comic-Con in the past with creators Mark Gatiss, Steven Moffat and Sue Vertue in attendance instead of Cumberbatch and his co-star Martin Freeman.
The annual Comic-Con event begins on 24 July and also includes a session from Warner Bros. featuring Peter Jackson's The Hobbit: The Battle of the Five Armies. The trilogy's final instalment also stars Cumberbatch and Freeman, although it's not yet clear if the former will stick around an extra couple of days for that panel on 26 July.
