He attended a question and answer session about his life and career at the Lyric Theater in Florida, and upon leaving was mobbed by autograph hunters armed with pictures of the 81-year-old actor with the beautiful Wood in their youth. And while he made no comment on the investigation, on stage he paid tribute to the actress wife he 'loved very much'. Back on the scene: Robert Wagner signs autographs for fans, including a photo of himself and dead wife Natalie Wood in Florida last month . Silence is golden: It was the 81-year-old's first appearance since it was announced police had reopened the investigation into Wood's death . Wagner recalled: 'One of the highlights of all time was . working with Natalie on a ‘Cat on a Hot Tin Roof’ … I loved her very . much.' He also shared a footage of himself and Wood cutting his 30th birthday cake. Wagner has kept a low profile since the announcement police were reopening the . investigation into the mysterious death of his wife Natalie Wood. Wood died November 29, 1981 while she was boating with her husband, Robert Wagner, and actor Christopher Walken, off Catalina Island in California. Sealed lips: Robert Wagner refused to comment on speculation about Natalie Wood's death when he arrived at a theatre in Florida today . The couple had reportedly argued that night, but there was no determination of foul play following Wood’s death. The Los Angeles County coroner’s . office said the actress could have slipped and fallen into the water . while trying to secure a dinghy to the boat. Seen earlier in the day Wagner refused to speak about the developments. The Austin Powers star also refused to talk about accusations by the boat's captain he had a role in her death and covered up the events of the night. Despite the recent reopening of the case, so far the actor is not said to be in consideration as a suspect. Defensive: Mr Wagner was reported to have been shocked when he was asked about recent developments in the case . A little less conversation: Ironically he was at the theatre as he is staging a show titled A Conversation with Robert Wagner . It follows the captain of the yacht from which his then wife fell and drowned passing a polygraph test over his account of the incident. Dennis Davern, 62 , said he heard the West Side Story star rowing with her husband Mr Wagner minutes before she disappeared. He has said he believes the 81-year-old had a role in his late wife's death. Telling the truth: Dennis Davern has passed a polygraph test over his account of the night that Natalie Wood died . Davern had a lie detector test performed on him by examiner Howard Temple, who says that the results of the polygraph 'indicated he was telling the truth.' Temple told Good Morning America that Davern explained how after Wood’s death Wagner instructed him to not talk about the drowning. 'Davern made the statement that he stayed at the Wagner home … [was] told not to talk …Wagner paid for his therapy, and Davern could not leave the estate without bodyguards,' Temple relayed. When asked if Wagner, who has one daughter Courtney, 37 , with Natalie and is the adopted father of her child Natasha Gregson, 41 , from a Wood's previous marriage, should take responsibility for her death, Davern replied: 'Yes I would say so.' Married life: Robert Wagner and Natalie Wood attend an event in LA in 1980, a year before her tragic death . He also mentioned his own culpability, and recalled: 'We didn’t take any steps to see if we could locate her. It was a matter of don’t look too hard, don’t turn on search light, don’t call anyone.' Davern also admitted that he lied to officials in the initial police report. His motives for revealing this damning account of that fateful night are being questioned as he has co-authored a book about the actress’s death. He and Marti Rulli wrote the 2009 book Goodbye Natalie, Goodbye Splendour, about the circumstances surrounding the actress’ death at 43, just off the island of Catalina in California. He and Lana Wood, Natalie Wood’s sister, asked authorities to re-open the case last year, the latter believes that Natalie would never have willingly gone near the water because she was terrified of it. The Splendour: The infamous vessel as it is today . According to ABC news, detectives have now interviewed Marilyn Wayne, the witness who was aboard a ship 40 yards away that night in 1981. She claims she heard Wood screaming for help moments before she allegedly drowned off the coast of Catalina Island in California. 'They talked to me about what I remember from the case all those years ago,' Wayne told “Entertainment Tonight.” Actor Christopher Walken, now 68, with whom she was filming the movie Brainstorm, was also aboard the boat that night. The official cause of Wood’s death was determined to be accidental drowning, speculation has been rife about the exact details and the case remains one of Hollywood’s longest-running mysteries. Lifeguard: Roger Smith believes he could've saved Natalie if he'd been called earlier . Lifeguard Roger Smith, who found Wood's body in the water, has told Good Morning America that he believes the actress may have floated alive for hours. 'I could have saved her,' Smith said, adding that he was 'not called in time.' So far Wagner and Walken, the two men with Wood that night, are keeping quiet regarding the reopening of the case. When gossip website TMZ.com caught up with Walken in West Hollywood on Tuesday to ask him what he thinks about the reopening of the case, Walken said: 'I don’t know.' Wagner, best known for the series Hart to Hart,” is filming an appearance as a murder suspect on an episode of CBS’ NCIS this week. Convinced: Natalie's sister Lana fought for the case to be reopened .
