Hollywood star Liam Neeson will help the IRFU ratchet up their all-out charm offensive bid to host Rugby World Cup 2023 in Dublin on Tuesday.

Neeson has narrated a video entitled "Ready For The World" that the 2023 World Cup bid team will debut at Tuesday's bid unveiling at the Aviva Stadium.

The IRFU Ireland will reveal detailed logistics and plans for their bid at Tuesday's press conference, outlining potential venues and anticipated tourism and financial benefits of hosting the competition.

Ireland are battling it out with South Africa and France for the chance to stage the World Cup in seven years' time.

The IRFU has joined forces with the two Irish governments to build a bid. 

Global governing body World Rugby will decide the 2023 competition's destination in November 2017 - and Ireland will be the first of the three competing nations to map out their detailed hosting plans.

Ambassador Brian O'Driscoll will join an Taoiseach Enda Kenny, deputy first minister Martin McGuinness and bid board chairman Dick Spring in Tuesday's grand unveiling.

Ireland confirmed their intention to challenge to host the 2023 World Cup as early as December 2014, with IRFU chief executive Philip Browne even then able to estimate that €110million bill for the bid.

"For the Japan World Cup the guarantee tournament fee which has to be paid to Rugby World Cup is £96million," said Browne in December 2014.

"One assumes we are going to have to pay at least that, probably more."

The World Cup bid committee will be expected to give an update on the protracted redevelopment of Belfast's Casement Park GAA stadium.

The GAA is already on board for its stadia to provide the kind of vast attendance opportunities that will underpin Ireland's World Cup bid.

The likes of Croke Park will be crucial to Ireland's chances of staging the tournament, with the 82,000-capacity Dublin stadium surely lined up as a potential venue to host the final.

GAA bosses have already insisted Casement Park's redevelopment will be ushered through in time to underwrite the World Cup bid. But the IRFU and the bid team could provide further detail on that front this week.
