"I hate when people say they don't have strong feellings about something then proceed to spew offensive and ignorant ones. Jeremy Irons," Cumming tweeted.
However, Irons is adamant his comments have been misinterpreted and has now attempted to clarify his statements with a post on his official website.
"I am deeply concerned that from my online discussion with the Huffington Post, it has been understood that I hold a position that is anti-gay. This is as far from the truth," Irons wrote.
"I was taking part in a short discussion around the practical meaning of Marriage, and how that institution might be altered by it becoming available to same-sex partners.
"Perhaps rather too flippantly I flew the kite of an example of the legal quagmire that might occur if same sex marriage entered the statute books, by raising the possibility of future marriage between same sex family members for tax reasons.
"Clearly this was a mischievous argument, but nonetheless valid."
"I had hoped that even on such a subject as this, where passions run high, the internet was a forum where ideas could be freely discussed without descending into name-calling," Irons said.
