Gary Busey is overjoyed at the opening night of his musical Only Human with his partner Steffanie Sampson and mini-me son Luke Sampson Busey

He's had a highly publicized series of ups and downs, but things seem to be looking up for Gary Busey now.

The 75–year–old actor looked like he was on top of the world at the opening night party for his new Off-Broadway musical Only Human, in which he plays a zany version of the Christian God.

He was joined at the party by his longtime partner Steffanie Sampson, 45, as well as his lookalike son Luke Sampson Busey, nine.

Gary flashed his trademark grin as he hit the red carpet with his family.

He stuck to the dark color scheme with a pair of jeans, and he wore his hair swept back while sporting some ragged stubble for his performance.

The actress looked sleek in a long black dress, and she wore her caramel-colored tresses down in messy strands.

The two have been dating since 2008 and have so far decided not to tie the knot.

Also joining the couple was their son Luke, who bore a striking resemblance to his famous father.

He had on a cheeky gray shirt reading: 'We need more girls on Earth,' a reference to the musical.

Gary stars in the play as God, and the play begins prior to the invention of humankind.

He's only referred to as the Boss throughout the play and is joined by Jay (Jesus), Lou (Lucifer) and Maggie (Mary Magdalene).

The show combines low-key office humor with the story of how Lucifer was cast out of heaven, as well as how humans came to inhabit the Earth.

Acting alongside Busey were his co-stars Evan Maltby (Jesus), Kim Steele (Mary Magdalene) and Mike Squillante (Lucifer).

Evan mixed classy and casual with a black suit and a pale blue sweater, along with white tennis shoes.

Jack of all trades: Mike Squillante, who plays Lucifer, look rugged with his tousled hair and well-trimmed beard. He also co-created the story and wrote the pop–rock songs

He had on a black suit with an edgy black shirt covered in white splotches that was left unbuttoned at the top.

In addition to playing Lucifer in the show, he's also wrote the show's pop–rock songs and is co-credited with its story.
