Just saw actress Amy Adams do something incredibly classy. She gave her 1st class seat to an American soldier. I'm an even bigger fan now.

The five-time Oscar nominee then spent the five-hour flight in economy, where a fellow passenger, journalist Ernest Owens, snapped a selfie with her.

The star's father was a US serviceman and she grew up living on US military bases.

“I didn't do it for attention for myself. I did it for attention for the Troops,” Adams later told Inside Edition after landing in Los Angeles.

The 39-year old actress was in Detroit filming "Superman v Batman: Dawn of Justice".
