Daveed Diggs and Rafael Casal in Blindspotting.

Collin (Daveed Diggs), a man on his last few days of probation, faces a challenge when he not only witnesses a cop shooting a suspect in the back; he also winds up being in the presence of another person shooting off a firearm, multiple acts of violence, and more things that would get him thrown back in jail.

Did I mention that Blindspotting is a comedy?

Diggs, along with buddy Rafael Casal, wrote the script for what turns out to be one of the year’s better directorial debuts, by Carlos López Estrada. The two also share the screen together, with Casal turning in a breakout performance as Collin’s best friend and co-worker, an outspoken troublemaker who courts mischief with every word.

The final act includes some daring choices, and they pay off. Diggs and Casal have the potential to be a great writing/acting duo, and I am curious to see what comes next.

Blindspotting is available via online sources including iTunes and Amazon.com; it will be available on DVD and Blu-ray Nov. 20.
