John Travolta is flanked by daughter Ella Bleu, 18, and son Benjamin, eight, as they prepare to board the Orient Express during day out in Venice Professional concerns took a back seat on Wednesday morning as John Travolta focused on personal matters during an appearance in Venice. The Hollywood star was joined by his children, daughter Ella Blue and son Benjamin, as they prepared for a scenic train journey aboard the iconic Orient Express. Looking smart in a black blazer and jeans, Travolta, 64, was in high spirits as he posed for cheery snap his family before climbing aboard. The celebrated actor’s presence generated inevitable attention, and he ran the gauntlet admiring waiters in pristine white tunics as he passed by with his children. Flanking their famous father, Ella, 18, and Benjamin, eight – Travolta’s children with actress Kelly Preston - held his hands while making their way onto the train. Ella looked stylish in a black dress and ankle boots teamed with a distinctive mustard winter coat, while Benjamin appeared to follow Travolta's lead by wearing his own blazer and jeans combination. Travolta's latest appearance comes after he celebrated the 40th anniversary of what is arguably one of his most famous films, the legendary Grease. Grease was the highest grossing movie of 1978, with its soundtrack album selling over 28 million copies worldwide. Set at Rydell High, the movie followed the lives of the T-Birds and the Pink Ladies and is now one of the highest grossing musical films of all time. It cemented Travolta, who was fresh off the success of Saturday Night Fever the year before, as one of Hollywood's top leading men. The chart-topping film also provided an immense boost to Olivia Newton-John, who up until then, was known as a country music and pop singer. Grease, like Saturday Night Fever, was produced by the late Australian producer Robert Stigwood and marked the big screen debut of American director Randal Kleiser, who had previously directed Travolta in the 1976 TV movie The Boy in the Plastic Bubble. .
