Mark Ruffalo shares throwback pictures from 'Avengers' on Chris Evan's birthday

Hollywood star Mark Ruffalo sent birthday greetings to his Avengers co-star Chris Evans who turned 39 on Saturday.

"‪Happy birthday, ChrisEvans! Wishing you all the best today, bro," the Hulk actor wrote on Instagram where he shared a couple of pictures with the Captain America star.

One of the throwback pictures were apparently taken on the sets of the Avengers as it showed Evans donning Captain America's costume.

Chris Evan's role in the Avengers series came to an end with Avengers: Endgame that released last year.

The film became the highest-grossing movie of all time, a record previously held by James Cameron's Avatar.
