Two half-brothers - played by Ewan McGregor and Ethan Hawke - reunite to bury the father they both hated in the new trailer for Raymond & Ray.

The film had its world premiere at the prestigious Toronto International Film Festival in September, and it's set to play at the Busan International Film Festival and Chicago International Film Festival in October.

The film, written and directed by Rodrigo Garcia (Last Days in the Desert), debuting in theaters October 14 before arriving on Apple TV Plus October 21.

The trailer begins with Raymond (McGregor) knocking on Ray's (Hawke) door, telling his half-brother, 'Our father is dead.'

'His last wish was that his sons attend his funeral,' Raymond says, as Ray replies, 'You don't have to go. He's dead. He'll never know.' 

Ray puts down a coffee mug for Raymond, who takes it and says, 'You're a very tender man, you know that?' 

The half-brothers meet with their father's lawyer Mendez (Oscar Nunez), who says, 'Your father's last will. It was his wish that you dig his grave.'

This clearly perplexes both brothers, as Raymond can only muster, 'What?'

The brothers are both in a car as Raymond says, 'The old man was always screwing with us, but forgiveness is good,' as they're seen starting to dig the grave.

They're at the funeral home as Canfield (Todd Luiso) shows them the casket their father selected... an extremely plain wooden box, compared to the ornate caskets shown behind them.

'The cheapest man who ever lived,' Ray says, while another shot shows Raymond getting acquainted with Lucia (Maribel Verdu).

When Raymond asks how she knew their father, she said, 'We were lovers for awhile,' which causes Ray to nearly spit out his soup.

Another scene shows Kiera (Sophie Okenedo) asking Ray what he was like as a father, as he replies, 'The worst,' as Raymond and Ray are both seen fighting.

'Like a weight on my chest,' Ray adds, as Raymond is seen having a dream he's being buried alive, adding, 'Forgiveness is good.'

They are thrown for another loop when Lucia introduces Raymond and Ray to her young son and their brother, Simon, while they're digging the grave.

Raymond adds, 'We come from chaos. Our father was a monster. We repeat. We repeat,' though Ray responds, 'We don't have to.'

Ray is seen playing a trumpet at the funeral, flanked by Canfield and another character played by Vondie Curtis-Hall.

The trailer shows both brothers trying to walk on their hands - set to Charles Bradley's Changes - while Ray adds that both he and Raymond were 'connected at the hip' when they were growing up.

'And then, just being near each other is a reminder of all that pain,' Ray tells Kiera over drinks at a bar. 

Raymond tells Ray, 'I want to know what it feels like, letting it go,' while Ray is seen running after Kiera.

'But I'm scared it's gonna crush me,' Raymond adds, as he asks his brother to, 'come with me,' and Ray agrees.

'But it's gonna take a whole lot more than a hole in the ground to get the old man out of your head,' Ray tells him, as the trailer comes to an end.
