In addition to Syfy developing the live-action 'Superman' prequel TV series "Krypton" the network is also developing a pilot for the live-action series "Metropolis", focusing on 'Lois Lane' and 'Lex Luthor' before 'Clark Kent' entered the scene, looking at 13 new episodes to air in 2019:
"Gotham" executive producers John Stephens and Danny Cannon will launch "Metropolis", with Stephens writing the script and Cannon directing.
"...the pilot will follow 'Lois Lane' and 'Lex Luthor' as they investigate the world of fringe science and expose the city’s dark and bizarre secrets..."
"Tales of Metropolis" (2013) was a series of animated shorts as part of the 'DC Nation' block on "Cartoon Network", starring a different character every episode including 'Lois Lane'.
