Hamill, who returns as Luke Skywalker in 'Star Wars: The Last Jedi', will be saluted at the 13th annual event at Abrams' Bad Robot in Santa Monica, one night before the Oscars, reports The Hollywood Reporter.
"With Luke Skywalker to feature prominently in the Rian Johnson-directed 'The Last Jedi', Mark has spent a good deal of time filming in Ireland," Vargo said in a statement. "It seems especially appropriate that we honour him in 2018."
"Now it's my honour to be recognised by the US-Ireland Alliance in the same way. I find it meaningful because Ireland has always had a very special place in my heart, both personally and professionally. I know Trina Vargo's work with artists and scholars, and I'm so pleased to be a part this," he added.
