A corrupt judge was named after Grell on the show. Much of Grell's Green Arrow work has provided inspiration for Arrow, and characters he created including Shado and Eddie Fyers, have appeared in the series.

He even provided interior art for a couple of issues. Grell has done work with the series a few times, providing police sketches in an episode as well as drawing the official 2012 Comic Con 10-page sampler and a handful of covers for the Arrow digital comic. Among those to chime in quickly was Arrow executive producer Andrew Kreisberg. She followed up with a message to Green Arrow TV's Facebook page, asking fans for continued thoughts and prayers for the 65-year-old artist. 'Thank you for your thoughts and prayers!' 'As some of you know Mike Grell of Comic Book fame is my husband and he is doing better as he has been in the hospital,' Lauri La Sabre Grell wrote to Facebook.

His wife, then, took to social media to try and allay fan fears which-as Stan Lee learned when he cancelled a convention to get his pacemaker put in-can run wild quickly. 'Mike is OK, he's going to be resting up over the next few weeks and will be out on the road again to meet fans face to face.' 'Due to a brief hospital stay and guidance from his doctors, Mike Grell must cancel his appearance for the 2013 CopperCon,' wrote the site's webmasters. Mike Grell, the writer/artist who created The Warlord for DC Comics and redefined Green Arrow for a generation, was recently admitted to the hospital, and missed CooperCon last weekend as a result.
