Since the "Hawaii Five-0" finale premiered in April 2020, Alex O'Loughlin has been radio silent in the way of acting. The star has no social media and has remained very quiet about his personal life. Unfortunately, the Steve McGarrett actor has yet to pop up on the social media accounts of any of his fellow "Hawaii Five-0" co-stars, too, making his present-day whereabouts all the more mysterious.
In January 2021, O'Loughlin did an interview with PacBleu (via YouTube), where he discussed some of what he did during the height of the COVID-19 lockdowns. A lot of his time was spent working out with his family and maintaining his healthy lifestyle, which is particularly important after having suffered from an injury on set in season 2 of "Hawaii Five-0." He also mentioned that he is working on three scripts, one for television and two for film, but said they are nowhere near ready to be shared. O'Loughlin told PacBleu that the lockdown has been a nice time for him to take a break and focus on his family life and did not mention returning to acting any time soon.
O'Loughlin was a fan-favorite on the "Hawaii Five-0" reboot, and it is likely that if he does decide to return to acting, many fans will tune in to see what their favorite Lieutenant Commander is up to next.
