The council has agreed to commission a portrait of the Limerick hell-raiser which will be hung in City Hall.
Crowe, who described Harris as his hero, has written to Cllr John Gilligan saying the gesture to honour Harris was a “fine and noble” one.
In his letter, Crowe recalled how was supposed to watch the 2002 Ireland V Australia game with the Limerick born star, but he died shortly before the match day came.
Russell Crowe wrote: “While the game was being played, with all the ridiculous mistakes that Australians were making, it occurred to me that Richard might be participating from beyond the grave.”
He told Cllr Gilligan that he had “better pick a good painter or at least warn the artist there is a possibility of supernatural attendance in this work”.
Crowe also sent a song he recorded in memory of Harris, which he wrote on a beer mat in Dublin.
Cllr Gilligan said: “The song is called Mr Harris and I was delighted to receive it. I think that it is appropriate that a Limerick artist should do the portrait.”
Cllr Gilligan proposed the motion to have the portrait commissioned.
