It is great when your brother has your back and stands up for you. Not so great when he ends up posting a series of angry tweets in your defence. On Oscars night (28 February), Sylvester Stallone's younger brother, actor-musician Frank was very unhappy about the fact that his elder brother did not win the award for best supporting actor for his role in Creed, which instead went to Mark Rylance for Bridge Of Spies.

So he decided to vent out on Twitter with a series of angry posts directed at the Film Academy and even dragged Rylance into the mix.

By the next evening, Frank seemed to have realised that his attack was unwarranted and posted an apology to the best supporting actor, while still holding his ground about Sylvester being the more deserving nominee.

Fans of the Stallone brothers continued to discuss the event, arguing that Sylvester should have won. In his reply, Frank defended his earlier posts stating that he was "done responding to idiots".

"If you don't stick up for your family then who are you as a person," he added, with another post reading, "Now I'm having a Meltdown? When you stick up for your beliefs and family from nasty tweets. It's called fighting back. No PC here."

He even brought up the whole diversity issue the Academy has been facing.

Sylvester on the other hand kept things simple while addressing his brother's tweet tantrum. On Monday morning he uploaded a photo of himself on Instagram with a post saying, "I'm very happy and please understand my brother is so emotional because he is just very protective and only wants the best for me. Life is good!"
