John Logan is the show runner and is also the executive producer of “Penny Dreadful” along with Sam Mendes.
The first season of the show actually premiered at the South by Southwest Film Festival on March 9, 2014 and aired on April 28, 2014 on Showtime on Demand. But it was about a month later or on May 11, 2014 when the first episode of Season 1 aired on the Showtime channel.
While the first season only had eight episodes, Season 2 has been confirmed to have 10 episodes on Showtime. It premiered on May 3 and expects to have its series finale on July 5.
Just like its Season 1, the Season 2 premiere was first made available on April 19, 2015 through Showtime on Demand and YouTube, but it was about two weeks later when it finally premiered on the small screens on the Showtime channel.
