EDIT 03-20-13 -- Whoops, I am forced to correct myself. Apparently there was a Witchblade/Red Sonja crossover series just in the last couple of years. And that thing with Ash from Army of Darkness fighting the Marvel Zombies. Who knows, maybe I'm forgetting other things as well.
I like the King Kong suggestions. Not sure where you could go with it, but it'd be cool. This year would be the perfect time to do it too, since it's King Kong's 80th anniversary.
One character that, imo, Dynamite needs to persue is Doc Savage: Man of Bronze.
2013 is also the 80th anniversary of the Doc.
If my understanding is correct, and I am the first to admit I could be wrong. DC has lost the rights to Savage. Leaving them open for a quick and savy company to pick them up.
Given the excellent run Dynamite has had/and is having with their presentation of pulp characters, it would be a shame if they did not make a serious attempt to aquire the rights.
And The Avenger* too, while they're at it. Might as well go for the Street & Smith trifecta. Those three were always the "Big 3" pulp heroes to me (sorry, Spider and Black Bat). Of course The Avenger had a lot more success the second time around in the 1970s as a paperback reprint than he ever did in the 1940s, to the point where when the original pulp stories ran out, Paperback Library commissioned new ones from writer Ron Goulart. Strangely enough, The Spider and Black Bat (and other long-running pulp heroes like G-8 and Phantom Detective) never made much of a dent in the market in the 1960s-1980s mass-market paperback reprint era, even though they were vastly more popular in the 1930s and 40s. The irony there is that Paperback Library licensed the right to reprint The Avenger from Conde-Nast, while they actually owned the rights to the Ned Pines-published pulp heroes Phantom Detective, Black Bat, and Captain Future. Probably goes to show the importance of having a really strong cover artist like James Bama, Jim Steranko, or Peter Caras.
*If they can get around the fact that Marvel will object to them using the title "The Avenger" and DC may object to "Justice Inc."
I would like to see an updated Dick Tracy series, Lost in Space and a Warlord of Mars/Lord of the Jungle crossover.
new Lost in Space comics (based on the old show instead of the movie) would be awesome. as would Voyage to the Bottom of the Sea. i grew up with reruns of all the Irwin Allen shows and loved them. still do.
